RF, IF and Microwave Blocks

IF/RF section contains high-frequency blocks which generally are a part of more complex devices, but also they can be of independent use. Here you can find RF-synthesizers, frequency converters, couplers, detectors, switchers and so on.

Up / Down Converters ( 3 Articles )

Frequency converters are used to transfer signal from intermediate frequency (IF) to carrier (RF) of vice versa. Up Converters transfer signal from IF to RF, Down Converters – from RF to IF. Parameters of the RF Up/Down converters used to specify its characteristics are listed below.

RF input/output frequency range;
IF output/input central frequency;
IF signal bandwidth;
Noise figure (NF);
One-decibel compression point (P_1dB);
3-rd order interception point (IP₃);
Path gain;
Image rejection.

RF Synthesizers ( 3 Articles )

Frequency synthesizers are used for periodic signal synthesis with arbitrary frequency from signal of constant reference frequency. There’re some parameters of high-frequency synthesizers:

Output frequency range;
Min. frequency step;
Phase noise (dBc/Hz) at some offset from some specified central frequency;
Frequency stability (long term, short term, ageing) – depends of reference oscillator;
Harmonic level suppression;
SFDR (except harmonics);
Output signal level (or range).

I/Q Modulators ( 2 Articles )

Vector (quadrature) modulators are used to transfer complex signal in form I(t)+jQ(t) from zero in frequency domain to IF or carrier frequency. These modulators are also referred to as I/Q-modulators. They are specified by the following parameters:

RF output frequency range;
I/Q bandwidth (or max. baseband);
Quadrature phase error;
Amplitude imbalance;
Carrier suppression;
Signal-to-Noise ratio (SNR);
One-decibel compression point (P_1dB);
3-rd order interception point (IP₃);
Path gain.

I/Q Demodulators ( 1 Article )

Vector (quadrature) demodulators are used to transfer high-frequency (RF) signal to zero in frequency domain. They are also called I/Q-demodulators. One has the output signal in form I(t)+jQ(t), i.e. two output channels. The general parameters are listed below.

RF input frequency range;
I or Q channel band;
Quadrature phase error;
Noise figure (NF);
Input 3-rd order interception point (IIP₃);
