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 (P1dB);
    • 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 (P1dB);
    • 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);
