M/A-COM's new SMR-5550i meets the need for a low cost, high performance microwave receiver. The receiver offers all the necessary features for high data rate PCM/TDM reception while maintaining high pulse fidelity for RADAR interception. The SMR-5550i electrical design features the low group delay distortion, low phase noise characteristics and high dynamic range necessary in today's demanding signal environments. Through the use of "state of the art" commercial components coupled with a high volume production line, M/A-COM's SMR-5550i sets a new standard for performance-to-cost value in microwave signal reception.

The SMR-3822L Receiver, a member of the SMR-3000 family of high-performance synthesized microwave receivers, covers 0.5 to 18 GHz. An internal Spectrum Display Generator (SDG) generates data that can be used to develop RF Sweep and IF Pan spectrum displays on a remote workstation or laptop. The receiver provides simultaneous wideband IF outputs at 1 GHz (500 MHz bandwidth), 70 MHz (50 MHz bandwidth), and 160 MHz (80 MHz bandwidth) in addition to a post filtered 160 MHz IF output. All IF outputs have a non-inverted spectrum; in addition, there is operator selectable inversion of the IF up to 18 GHz tuned frequency.

The Model 388A IF to Tape/Baseband Converter provides the features necessary to meet today's wide range of signal down-conversion applications from conventional IF-to-tape conversion to high speed A/D signal recording. The unit offers maximum user flexibility and improved performance while maintaining a compact mechanical package. Features include the capability to process up to a 80 MHz signal bandwidth, tunable input and output center frequencies, and RS-232 or optional Ethernet 10/100BaseT control of all functions.

The Model 409 VLF-HF Multicoupler is a compact broadband unit which permits up to 16 receivers (409-02.) or eight receivers (409-03) to be coupled to a single antenna. A low noise input amplifier provides a nominal gain of 5 dB and achieves a wide dynamic range over a broad band covering the VLF and HF bands. Input circuitry provides protection under high ambient RF field conditions or from nearby lightning strikes.

The Model 410 HF Multicoupler is a compact unit which allows coupling of up to sixteen HF Receivers to a single antenna or to one of two switch selectable antennas. A low noise input amplifier provides a nominal gain of 5 dB and achieves a wide dynamic range over the entire HF band. Input circuitry provides protection under high ambient RF field conditions or from nearby lightning strikes.

The Model 414 VHF/UHF Multicoupler is a compact unit which allows up to 14 VHF/UHF receivers to be coupled to a single antenna or to one of two switch selectable antennas. The input signal drives a wideband amplifier which achieves wide dynamic range and high isolation with amplifier gain sufficient to overcome incidental losses.

The Model 417-01 covers the 30 to 6000 MHz frequency range. The use of a wideband, high dynamic range amplifier results in minimum distortion over the specified frequency range and gain sufficient enough to overcome incidental losses. The Model 417-01 is available with eight outputs in a 1U, half-rack chassis permitting convenient side-by-side installation of two units.

The Model 418 covers the 20 to 3000 MHz frequency range. The use of a wideband, high dynamic range amplifier results in minimum distortion over the specified frequency range and gain sufficient enough to overcome incidental losses. The Model 418 is available with eight outputs in a onehalf rack chassis permitting convenient side-by-side installation. This unit is also available in a full-rack version with 16 outputs.
