Main

If you choose Mixer Type as Downconverter, then the blockset computes the mixer output frequency, f_out, from the mixer input frequency, f_in, and the local oscillator frequency, f_lo, as f_out = f_in – f_lo.
If you Mixer Type as Upconverter, then f_out = f_in + f_lo.

Note

For a downconverting mixer, the local oscillator frequency must satisfy the condition f_in – f_lo ≥ 1/(2t_s), where t_s is the sample time specified in the Input Port block. Otherwise, an error appears.

Network Parameters

The network parameter values all refer to the mixer input frequency. If network parameter data and corresponding frequencies exist as S-parameters in the rfdata.data object, the General Mixer block interpolates the S-parameters to determine their values at the modeling frequencies. If the block contains network Y- or Z-parameters, the block first converts them to S-parameters. See Map Network Parameters to Modeling Frequencies for more details.

RF Blockset™ Equivalent Baseband software computes the reflected wave at the mixer input ( $b_{1}$ ) and at the mixer output ( $b_{2}$ ) from the interpolated S-parameters as

$[\begin{matrix} b_{1} (f_{i n}) \\ b_{2} (f_{o u t}) \end{matrix}] = [\begin{matrix} S_{11} & S_{12} \\ S_{21} & S_{22} \end{matrix}] [\begin{matrix} a_{1} (f_{i n}) \\ a_{2} (f_{o u t}) \end{matrix}]$

where

$f_{i n}$ and $f_{o u t}$ are the mixer input and output frequencies, respectively.
$a_{1}$ and $a_{2}$ are the incident waves at the mixer input and output, respectively.

The interpolated S₂₁ parameter values describe the conversion gain as a function of frequency, referred to the mixer input frequency.

Active Noise

You can specify active block noise in one of the following ways:

Spot noise data in the data source.
Spot noise data in the block dialog box.
Spot noise data (rfdata.noise) object in the block dialog box.
Noise figure, noise factor, or noise temperature value in the block dialog box.
Frequency-dependent noise figure data (rfdata.nf) object in the block dialog box.

The latter four options are only available if noise data does not exist in the data source.

If you specify block noise as spot noise data, the block uses the data to calculate noise figure. The block first interpolates the noise data for the modeling frequencies, using the specified Interpolation method. It then calculates the noise figure using the resulting values.

Phase Noise

The General Mixer block applies phase noise to a complex baseband signal. The block first generates additive white Gaussian noise (AWGN) and filters the noise with a digital FIR filter. It then adds the resulting noise to the angle component of the input signal.

The blockset computes the digital filter by:

Interpolating the specified phase noise level to determine the phase noise values at the modeling frequencies.
Taking the IFFT of the resulting phase noise spectrum to get the coefficients of the FIR filter.

Note

If you specify phase noise as a scalar value, then the blockset assumes that the phase noise is the phase noise is constant at all modeling frequencies and does not have a 1/f slope. This assumption differs from that made by the Mathematical Mixer block.

Nonlinearity

If power data exists in the data source, the block extracts the AMAM/AMPM nonlinearities from it.

If the data source contains no power data, then you can introduce nonlinearities into your model by specifying parameters in the Nonlinearity Data tab of the General Mixer block dialog box. Depending on which of these parameters you specify, the block computes up to four of the coefficients $c_{1}$ , $c_{3}$ , $c_{5}$ , and $c_{7}$ of the polynomial

$F_{A M / A M} (s) = c_{1} s + c_{3} {| s |}^{2} s + c_{5} {| s |}^{4} s + c_{7} {| s |}^{6} s$

that determines the AM/AM conversion for the input signal $s$ . The block automatically calculates $c_{1}$ , the linear gain term. If you do not specify additional nonlinearity data, the block operates as a mixer with a linear gain. If you do, the block calculates one or more of the remaining coefficients as the solution to a system of linear equations, determined by the following method.

The block checks whether you have specified a value other than Inf for:
- The third-order intercept point ( $O I P 3$ or $I I P 3$ ).
- The output power at the 1-dB compression point ( $P_{1 d B, o u t}$ ).
- The output power at saturation ( $P_{s a t, o u t}$ ).
In addition, if you have specified $P_{s a t, o u t}$ , the block uses the value for the gain compression at saturation ( $G C_{s a t}$ ). Otherwise, $G C_{s a t}$ is not used. You define each of these parameters in the block dialog box, on the Nonlinearity Data tab.
The block calculates a corresponding input or output value for the parameters you have specified. In units of dB and dBm,

$\begin{matrix} P_{s a t, o u t} + G C_{s a t} = P_{s a t, i n} + G_{l i n} \\ P_{1 d B, o u t} + 1 = P_{1 d B, i n} + G_{l i n} \\ O I P 3 = I I P 3 + G_{l i n} \end{matrix}$
where $G_{l i n}$ is $c_{1}$ in units of dB.
The block formulates the coefficients $c_{3}$ , $c_{5}$ , and $c_{7}$ , where applicable, as the solutions to a system of one, two, or three linear equations. The number of equations used is equal to the number of parameters you provide. For example, if you specify all three parameters, the block formulates the coefficients according to the following equations:

$\begin{matrix} \sqrt{P_{s a t, o u t}} = c_{1} \sqrt{P_{s a t, i n}} + c_{3} {(\sqrt{P_{s a t, i n}})}^{3} + c_{5} {(\sqrt{P_{s a t, i n}})}^{5} + c_{7} {(\sqrt{P_{s a t, i n}})}^{7} \\ \sqrt{P_{1 d B, o u t}} = c_{1} \sqrt{P_{1 d B, i n}} + c_{3} {(\sqrt{P_{1 d B, i n}})}^{3} + c_{5} {(\sqrt{P_{1 d B, i n}})}^{5} + c_{7} {(\sqrt{P_{1 d B, i n}})}^{7} \\ 0 = \frac{c_{1}}{I I P 3} + c_{3} \end{matrix}$
The first two equations are the evaluation of the polynomial $F_{A M / A M} (s)$ at the points $(\sqrt{P_{s a t, i n}}, \sqrt{P_{s a t, o u t}})$ and $(\sqrt{P_{1 d B, i n}}, \sqrt{P_{1 d B, o u t}})$ , expressed in linear units (such as W or mW) and normalized to a 1-Ω impedance. The third equation is the definition of the third-order intercept point.
The calculation omits higher-order terms according to the available degrees of freedom of the system. If you specify only two of the three parameters, the block does not use the equation involving the parameter you did not specify, and eliminates any $c_{7}$ terms from the remaining equations. Similarly, if you provide only one of the parameters, the block uses only the solution to the equation involving that parameter and omits any $c_{5}$ or $c_{7}$ terms.

If you provide vectors of nonlinearity and frequency data, then the block calculates the polynomial coefficients using values for the parameters interpolated at the center frequency.

Operating Conditions

Agilent^® P2D and S2D files define block parameters for several operating conditions. Operating conditions are the independent parameter settings that are used when creating the file data. By default, the blockset defines the block behavior using the parameter values that correspond to the operating conditions that appear first in the file. To use other property values, you must select a different operating condition in the General Mixer block dialog box.
