Leonardo DRS SI-9135-1/2 3U cPCI VHF/UHF Tuners

  • Intercepts Weak Signals in the Presence of Multiple Strong Signals
  • Up to 9 Phase-Coherent Channels w/o LOD Module
  • Small Size, Weight and Power (SWAP)
  • Wideband Tuner in a Single-Slot 3U cPCI Card


The Leonardo DRS SI-9135-1/2 3U cPCI VHF/UHF Tuners are 3U CompactPCI (cPCI) tuners that provide conversion of RF signals between 20 and 3000 MHz to an analog IF output centered at 70 MHz with an instantaneous bandwidth of 30 MHz. The tuner has a minimum tuning speed of 500 microseconds, performing fixed tuning with a resolution of 100 kHz and frequency scanning with a resolution of 1 MHz. Its small size, weight and power make it ideal for systems having limited space. Optimized to interface with Analog Devices AD664X wideband analog-to-digital converters, the SI-9135-1/2 makes available scan-friendly tune strobe/ trigger inputs and outputs that can speed frequency transitions during channel step or F1-to-F2 sweep operations.

The SI-9135-1/2's internal local oscillator distribution (LOD) mechanism allows it to share 1st and 2nd LOs with other tuners without an external LO distribution module.This makes possible a configuration of nine phase-coherent channels. These operational features and the SI-9135-1/2's preselector, low phase noise synthesizers, channel-to-channel phase tracking, and excellent dynamic range make it ideal for signal intercept or beamforming systems.

Product Family: SI-9135-1, SI-9135-2, SI-9135, S1-9135, S1-9135-1, S1-9135-2
