Antennas
Circularly Polarized Antenna
The model 470M1 is a compact highly efficient, circularly polarized antenna that provides hemispherical omni-directional coverage. The Model 470M1 has a VSWR of 1.5:1 maximum, nominal gain of -1 dBiC at the horizon and operates at RF power of 200 W CW. This antenna also employs a unique approach to generate circular polarization from a single linearly polarized input. Model 470M1 operates in the C-band, but can be scaled for other frequency bands of operation; contact Cobham Sensor Systems (Baltimore) for additional parameters. The antenna is five inches in diameter with a height of seven inches and the unit can withstand internal pressure of 10 psi. Model 470M1 has a WR187 connector and the antenna is qualified for a high mechanical shock environment.

Miniature Frequency Synthesizers
The SLX and LX Series miniature frequency synthesizers are custom-designed to utilize 3 or 3.3 V inputs to meet the stringent low power consumption requirements of short range and battery powered wireless systems. The SLX and LX units feature extremely low power consumption (900 MHz, +3 V at 15 mA, typical) and typical power outputs of -5 dBm (up to +7 dBm, optional). The units also feature low spurious, low harmonics and exceptionally low phase noise. Available with operating temperature ranges of -40º to +85ºC, the units are designed as cost-effective, surface-mount packages and can be fixed-frequency or programmable in bands from 50 MHz to 6 GHz, with extremely low phase noise (<-110 dBc/Hz at 100 kHz offset, at 400 MHz).

Miniature Frequency Synthesizer
The SLSM5 is a new family of frequency synthesizers that operates to 12.5 GHz and covers up to octave bandwidths. This synthesizer features excellent phase noise (-95 dBc/Hz at 10 kHz at X-band) and excellent spurious performance (-60 dBc minimum). With 1 kHz steps and frequency controlled via convenient RS485 interface this synthesizer is a system friendly component. The SLSM5 operates on an external 10 MHz input or an internal TCXO. Only a single +5 V supply is needed to power this miniature (2.5" × 2.5" × 0.6") unit.

High Resolution Synthesizers
The MTS2500 series of high resolution synthesizers combine the latest in DDS and multi-loop synthesizer technologies with a high performance VCO to provide as low as 1 Hz step size, ultra low phase noise, wide bandwidth performance and low spurious, while permitting for increased loop bandwidth, faster settling time and higher stability under vibration. Several models are available covering wide frequency bands, the MTS2500-110250-10 (1.1 to 2.5 GHz), MTS2500-200400-10 (2 to 4 GHz) and MTS2500-300600-10 (3 to 6 GHz). Power consumption is less than 2.0 W. The low resolution offered by the MTS2500 series is ideal for applications in imaging equipment such as radar and magnetic resonance.

Test Equipment
Reverse Recovery Tester
The AVR-CD1-B is a high performance, GPIB and RS232-equipped instrument intended for reverse recovery time testing of diodes and other semiconductor devices. The AVR-CD1-B applies a forward bias pulse of +0.1A to +10A to a device under test (DUT). At the end of that pulse, the current ramps downward at an adjustable rate of 100 to 200 A/us until the diode stops conducting. The current waveforms generated by this instrument are suitable for MILSTD-750E Method 4031.4 Test Condition D tests. Standard and customized jigs for different device packages are available.
