Efficient Design and Analysis of Airborne Radomes
The models EP1400SJ and EP1500SJ programmable oscillators offer 5.0 and 3.3 V in the 1 to 125 MHz and 1 to 106.2 MHz frequency ranges, respectively. Housed in a 9.8 mm x 14 mm x 4.7 mm plastic surface-mount j-lead package, these oscillators utilize a proprietary design and an exclusive programming method that offer a quick and cost-effective oscillator solution. The models are offered in a 14-pin DIP or eight-pin DIP hermetically sealed package and a ceramic SMD package. Operating temperature range is -20° to +70°C or -40° to +85°C and storage temperature range is -55° to +125°C.

High Performance Oscillator
The narrowband MicroYIG™ high performance oscillator delivers output frequencies from 2 to 10 GHz and provides an output power between 0 and +5 dBm. The coarse frequency is set with a small permanent magnet requiring no current, and fine-tuning is accomplished with a FM coil. Amplification of the signal is best handled by the end user via an inexpensive surface-mount amplifier. The unbuffered oscillator is available in a TO-8-style package for board mounting and a connectorized package, which allows the MicroYIG to be mounted to any system chassis.

3930 - 4200 MHz VCO
The model V910ME01 VCO operates in the 3930 to 4200 MHz frequency range with a tuning voltage of 1.5 to 11 V DC and covers the 270 MHz bandwidth with an average tuning sensitivity of 45 MHz. This rugged device conserves energy by operating from a 5 V DC supply while drawing only 16 mA and offers the end user 1 ±3 dBm of output power into a 50 W load. Input capacitance is 50 pF (max), phase noise is -86 dBc/Hz at 10 kHz offset and second harmonic suppression is -20 dBc (typ). Operating temperature range is -35° to +80°C. The VCO is best suited for automated surface-mount assembly and reflow and measures 0.50" x 0.50" x 0.13". Price: $15.95. Delivery: six weeks.
