The SI-9136BN is a dual-channel wideband VHF/UHF tuner that provides independent and/or phase-coherent conversion of RF signals between 20 and 3000 in a 6U VME single-slot module. The SI-9136BN’s two tuner channels each produce two analog IF outputs: a wideband IF output and a baseband IF output.
The SI-9136BN provides ten configuration options that offer independent and phase-coherent/non-phase coherent operations, baseband IF output choices and digitized IF output choices. For external digitizer applications, the tuner’s analog outputs are optimized to interface with the Analog Devices AD664X series of wideband A/D converters. See configuration options.
Phase-coherent configurations of the SI-9136BN feature an internal Local Oscillator (LO) Distribution assembly that allows it to accept or to provide first and second LOs to or from other tuners. This enables system configurations of up to eight phase-coherent channels when used in conjunction with an LO distribution module such as the SI-7100 or SI-7101. The low phase noise and channel-to-channel phase tracking make the tuner an ideal solution for direction finding or beam forming applications.
