L-band Coaxial Resonator Oscillator Delivers Extremely Low Phase Noise for Test Equipment and Digital Radio Applications

Featuring: Extremely low Phase Noise, High Output Power, Narrow Band, Excellent Second
Harmonic Suppression, RoHS Compliant

SAN DIEGO, April 14, 2008: Z-Communications, Inc. is proud to announce the introduction of their new lead free, RoHS compliant, coaxial resonator oscillator (CRO1680A-LF) in L band (1680 MHz) featuring extraordinary low phase noise (typ) performance of -120dBc/Hz @10kHz offset. This unique design offers excellent (typ) 2nd harmonic suppression of -20dBc with a typical tuning sensitivity of 4 MHz/V and covers the band between 0.5- 4.5 V. It is designed to provide 8dBm output power (typ) at 5Vdc supply while drawing 30mA (typical) over the extended operating temperature range of -40º to 85ºC. CRO1680A-LF is ideally suited for narrow-band applications that require excellent phase noise performance.

CRO1680A-LF comes in Z-COMM's industry standard MINI package measuring 0.50 in. x 0.50
in. x0.22 in. This amazing VCO is ideal for automated surface mount assembly and reflow. This is available in tape and reel packaging for production requirements.
