The HMC430LP4 provides a +2 dBm buffered output and low phase noise of -103 dBc/Hz at 100 kHz offset over 5.0 to 5.5 GHz. The HMC431LP4 provides a +2 dBm buffered output and low phase noise of -102 dBc/Hz at 100 kHz phase noise offset over 5.5 to 6.1 GHz. The phase noise performance of both products is good over temperature, shock and process due to the monolithic structure of the oscillators.

Direct Synthesizer

The PTS 1600 is a direct synthesizer, combining analog and digital technologies. It has good close-in phase noise as well as the ability to switch rapidly from one frequency to another. High speed remote control is provided through the standard TTL-level parallel interface port, but for easy integration into testing environments a GPIB interface is also available. By employing dedicated control hardware, the GPIB interface still provides 50 ms or better frequency switching. The PTS 1600 features a keyboard and LCD display, with resolution of 1 Hz. It reproduces the accuracy and stability of an internal frequency standard or accepts 5 or 10 MHz external standards. Price: $10,000. Delivery: 12 weeks ARO.

Environmentally Controlled Cabinet

The NEMA Type 3R rated environmentally controlled cabinet (ECC) can extend the life of critical microwave systems, radio equipment, DC power systems and more by avoiding extreme temperature changes. The ECC consists of an internal rack suitable for 19" or 23" rack mounted equipment and optional insulation. The optional air conditioner provides a cool, dehumidified environment for electronic equipment with a "closed-loop" design. The forced air heater works with the air conditioner to provide complete climate control, no matter what the weather. The optional insulation provides an extra layer of protection for temperature-sensitive equipment in extreme environments.

Power Amplifier Module

The model 5303075 is a 0.8 to 4.2 GHz, 1.5 W power amplifier module. This multi-octave highly linear amplifier module is ideally suited to boosting the output power from signal/waveform generators by more than 10 dB. Model 5303075 covers all the major communications bands, along with Bluetooth, 802.11b and the UHF radar bands. It can withstand +20 dBm of input power indefinitely without damage. Likewise, the output can tolerate reflected power at 100 percent rated output power without damage. Needing only a single 12 VDC power supply, this compact lightweight module comes with fixing holes for fastening to a cold plate, or it can be provided ready mounted on a heatsink complete with cooling fans.
