Integrated Microwave Assembly
The model D6040-921 integrated microwave assembly is designed for use in an airborne radar warning receiver. The highly integrated unit covers a broad frequency range (C-band through Ku-band) and contains two bipolar VCOs, one push-pull VCO, three lowpass filters, one bandpass filter, four MMIC amplifiers and two SP2T PIN-diode switches. The assembly operates over a temperature range of –54° to +95°C and features active temperature stabilization utilizing floating modules for DC power conservation. The assembly features hermetically sealed subassemblies and is designed to full military requirements. Size: 5.7" x 3.6" x 1.7".

Surface-mount OCXOs
 The model OX-5000 oven-controlled crystal oscillator (OCXO) withstands infrared solder reflow temperatures up to 300°C for 3 s during circuit board fabrication, making the units suitable for use with a variety of infrared solder reflow procedures. Frequency stability over the temperature range from 0° to +60°C is within +/-0.1 ppm or better. Stability vs. +/-10 percent VCC variation is within +/-0.25 ppm. Stability vs. +/-10 percent load variation also is within +/-0.25 ppm. Long-term stability is better than +/-0.3 ppm/year. The unit operates from a single +5 V supply and outputs a CMOS square wave from 0.4 to 4 V. Rise and fall times are better than 10 ns. Size: 1.000" x 0.866" x 0.453". Price: $85 to $200 (1000). Delivery: 10 to 14 weeks (ARO).
