Interad Introduces Modular HF Receiver System
The Model 3100 sets new performance standards with:
Phase Coherence
No Local Oscillators
High Dynamic Range
400 Mbps Firewire Output Connection
MELFA, VA - September 22, 2003 - Interad Ltd. announced today a new HF Receiver System, a stellar addition to their broad family of receivers, tunable filters and antenna systems. The Model 3100 offers unprecedented performance in HF receiver systems that cover the range of 10 kHz to 30 MHz.
Designed for surveillance and monitoring of RF communications in this frequency range, the Model 3100 features up to eight dual-channel analog RF receiver modules with user-configurable bandwidth. Direct antenna connections to the system are also user-configurable.
The Model 3100 system employs a unique design that does not use local oscillators
as is common with legacy superheterodyne designs. The desired frequency coverage is user- determined by the bandpass filters of the receiver modules. The absence of local oscillators results in receivers that are naturally phase-coherent. In addition, the spurious-free dynamic range is improved, because of the absence of sum and difference frequency products associated with the mixing process in a local oscillator.

Benefits
By offering user-configurable features such as frequency coverage and antenna connections, Model 3100 addresses diverse needs and can meet the application requirements of a vast majority of Interads customers. The absence of local oscillators enables Model 3100 to achieve a minimum guaranteed dynamic range of 80 dB, with 90 db being most typical. These specifications are unheard of in the HF receiver market.
More Features
The system includes up to eight Digital Firewire modules. This module includes dual A/D converters and four IEEE-1394a Firewire transceivers for direct connection to Pentium PC, SUN, or other workstations for further signal processing and analysis.
The system also includes low-noise amplifiers with programmable gain to accommodate different antenna signal levels. It also includes digital downconverters to facilitate receiver
tuning to the desired frequency and recovery of the information signals. These baseband signals are available as I and Q complex data through the Firewire connections.
The Interad 3100 System clearly sets new performance standards in HF receivers and it does so at very competitive prices. This turnkey system is ready to be connected to antennas and workstations. It thus offers an integrated end-to-end approach to surveillance and monitoring of RF communications in the HF range. The system can interface with any standard workstation with a Firewire connection to perform analysis functions such as detection, spectrum analysis, or direction finding.
The Model 3100 is immediately available with U.S. delivery of 12--16 weeks ARO.
