Multicouplers

MAVD05D

The MAVD05D-30-4-4X6-01 Video Multicoupler is intended for use with analog Video (0 to 2V) and TTL (0 to 5V) distribution systems. It provides a low cost means to provide four channels of RF or TTL Logic signals from an antenna or other source to eight individual loads. It is suitable for use with signals from DC to 50MHz at output levels to 4.8VDC into 93?. The unit is specified to operate from DC to 30MHz and is fully tested to assure compliance over that range.

RFDU05

The RFDU05-01-8N RF distribution unit provides a low cost means to provide an RF signal from an antenna or other source to eight individual loads. It is suitable for use with signals from below 50MHz to over 500MHz at levels up to -10dBm. The unit is specified to operate over the 200MHz to 350MHz frequency range and tested to assure compliance over that range.

Receivers

LCR100

The LCR100 series of tuners/receivers provide a low cost solution for an assortment of military and commercial applications. The double conversion superhetrodyne receiver with integral synthesizer can be configured with a 160 MHz IF output with a 100 MHz bandwidth or a 1 GHz IF output with a 500 MHz bandwidth. The small, lightweight tuner/receiver covers the frequency range from 0.5 to 18 GHz, with a tuning step size of 1 MHz.

RFS2000CSREDM

Mid-Atlantic RF Systems, Inc. has developed a new RX system for a performance upgrade of an LCR100 Tuner/Receiver. The upgrade enables the LCR100 Tuner/Receiver to meet the relevant operating specifications of competitors’ receivers at a reduced cost. The performance upgrade improves the present design of the LCR100 Tuner/Receiver in two areas. The first area is a modification of the design configuration to provide a simultaneous 160 MHz IF output and a 1 GHz IF output.

Switches

SPM01C

An absorptive single pole, high isolation single throw RF switch. The model SPM01C offers high speed performance over a wide frequency range. Both ports are matched in either state and the switch is controlled by an integral TTL compatible driver. Connectors are standard SMA for the RF ports and SMC for the logic input. The unit is powered by +5 VDC and -5 VDC.

DPM01C

An absorptive single pole, double throw RF switch. The model DPM01C offers high speed performance over a wide frequency range. Both ports are matched in either state, and the switch is controlled by an integral TTL compatible driver. Connectors are standard SMA for the RF ports and SMC for the logic input. The unit is powered by +5 VDC and -5 VDC.

Synthesizers

RFS9685-428-1B

A 406 to 450 MHz frequency synthesizer, tunable in 100 kHz steps, with an adjustable modulation input. Parallel input logic, power and modulation are supplied through a 15-pin D-Sub connector. The RF output connector is SMA (F). External FM adjustment is provided by a potentiometer. Custom designs can also be designed to meet your specifications.

RFSU-9215B

A Phase-Locked Loop (PLL) synthesized RF source operating from 200.000 MHz to 250.00 MHz. The unit operates with an external 10 MHz reference applied. The output frequency is TTL controlled, in 5 MHz increments, through a 9 pin D-Sub connector.

RFSU-9215C

A Phase-Locked Loop (PLL) synthesized RF source operating from 250.000 MHz to 300.00 MHz. The unit operates with an external 10 MHz reference applied. The output frequency is TTL controlled, in 5 MHz increments, through a 9 pin D-Sub connector.

DS-120B

A complete DDS-based frequency synthesizer with a self-contained clock and reference TCXO. It operates from 5 MHz to 120 MHz, TTL controlled through a 37 pin D-sub connector. A 9 pin D-Sub connector provides power and reference select lines.

SYNSN45

A dual loop S-band Stable Local Oscillator (STALO) tunable in 1 MHz steps via serial port. A thumbwheel switch, RS232 or custom interface for frequency control are optional. The unit exhibits excellent phase noise, frequency stability and low power consumption.

Tuners

TUN2-LM01

The TUN2-LM01 is a dual L-band single-conversion tuner designed for use in Microwave Radios. The operating frequency range spans from 1.71 ~ 1.84 GHz with the low band at 1.71 GHz ~ 1.75GHz and the high band at: 1.80 GHz ~ 1.84GHz.

TUN8-LM02

The Low Noise Amplifier and Switched Filter Banks set the Noise Figure and provide superior selectivity. Chip and wire in conjunction with surface mount technologies and multiplayer structures are employed and mixed to not only achieve the receiver parameters such as the low Noise Figure but also to reduce module cost wherever possible. The filter bank selectivity allows communication when in the presence of collocated L-Band frequency hopping radios and other sources of interference.
