Product Description

Compact Wideband VHF-UHF Receiver

The CA7851 is a high performance dual conversion super heterodyne receiver for radio monitoring and communications surveillance.

True Wideband Stare

The CA7851 has the ability to continuously digitise 100 MHz of spectrum in real time.

Digital Drop Receivers

Configure multiple digital drop receivers (DDRs) for simultaneous processing of wanted signals.

Customisable DSP Resources

Add software defined functionalist to dedicated customisable digital signals processing resources.

Phase Coherent

Synchronise multiple CA7851 units for Super Resolution DF, MIMO and and advanced signal enhancement techniques.

Precision Time-Stamping

Precision time-stamping with for TDOA (Time Difference of Arrival) Geo-Location.

Advanced RF Architecture

  • Robust performance in strong signal environments with integrated sub-octave preselector
  • Selectable modes: normal mode or high linearity mode, allowing configuration for optimum performance
  • Extremely stable group delay and absolute delay characteristics - crucial for enduring DF accuracy
  • Capable of synchronising with multiple units for phase coherent operation

Full Bandwidth Processing

The CA7851 is capable of streaming full bandwidth VITA 49 I/Q data of 10 GigE Ethernet in real time.

Customisable Digital Signal Processing

On-receiver software defined functionality can include: channellisation, demodulation, and automatic signal detection. For system integrators, the CA7851 has dedicated processing resources enabling upgrades with software defined functionality.

Rugged Carrier Chassis

The CAM91579 Dual Receiver Carrier Chassis is the recommended option for mounting multiple receivers into 19" equipment racks for mobile or static use. The rugged carrier chassis CAM91579 has been designed to meet MIL-STD-810G in the following categories:

  • High Temperature (Method 501.5, Proc. II, Cat. A2 (ambient))
  • Low Temperature (Method 502.5, Proc. II, Cat. C1 (ambient))
  • Vibration (Method 514.6, Proc. I, Cat. 4)
  • Acoustic Noise (Method 515.6, Proc. 3)
  • Shock (Method 516.6, Proc. VI)
