Aeroflex Raises Frequency of PN9276 Microwave Down Converter to 50GHz

10/10/2005 - Aeroflex has boosted the frequency of the PN9276 microwave down converter to 50GHz to enable phase noise testing for higher frequency applications. The Aeroflex PN9276 microwave down converter, first launched in June 2005, works with the company’s PN9500 to provide the industry’s best noise performance. Aeroflex phase noise products provide a unique combination of high bandwidth with low noise performance suited for radar, commercial wireless, satellite terrestrial microwave links, and calibration labs. The Aeroflex PN9276 is a 1 to 50GHz down converter that plugs into any Aeroflex PN9000 phase noise tester or PN9500 wideband jitter and noise analyzer.

Because of the IF (intermediate frequency) range, the PN9276 with the PN9500 system allows phase noise measurements up to 200MHz offset, the highest in the industry. This combination allows system sensitivity testing that is only available from Aeroflex. The “Smart Converter” scheme employed by Aeroflex in the down converter’s architecture offers a noise floor performance as low as –168dBc/Hz up to 2GHz. Performance at 9GHz is –95dBc/Hz at 100Hz offset, -131dBc/Hz at 10kHz offset, and –159dBc/Hz at 10MHz offset.

The PN9276 down converter includes a microwave mixer and a low noise YIG-based 100MHz step synthesizer. This synthesizer generates a 4GHz to 9GHz signal from a 100MHz crystal oscillator phase-locked on a 10MHz crystal oscillator. This provides a low noise reference close in and far away from the carrier without loss of spectral purity. Phase noise specifications for the PN9276 come in three modes—wide, narrow and standard—corresponding to three locking bandwidths for the output microwave YIG oscillator. Wide mode is optimized for the lowest close-in noise, up to 100KHz from the carrier. Narrow mode is optimized for the lowest noise far away from the carrier. Standard mode makes the best compromise of wide and narrow modes.

The PN9276 microwave down converter is available immediately upon receipt of order and is shipping now. The PN9276 is available in four versions: the PN9276-00 1 to 18 GHz down converter, the PN9276-01 1 to 26.5 GHz down converter, the PN9276-02 1 to 40 GHZ and the PN9276-03 1 to 50 GHz down converter.
