L-band VCO comes in a tiny package

December 17, 2015 // By Jean-Pierre Joosting
The model USSP1730-LF from Z-Communications is an RoHS compliant VCO (Voltage Controlled Oscillator) in the L-band that operates from 1715 to 1745 MHz within a tuning voltage range of 1 to 4 Vdc.

This small VCO features phase noise of -94dBc/Hz at 10 kHz offset while operating off a 5 Vdc supply and typically drawing 19 mA of current.

The low cost USSP1730-LF provides the end user a nominal output power of 3.5 dBm into a 50Ω load while operating over the industrial temperature range of -40 to 85ºC. This high performing VCO suppresses the second harmonic to better than -25 dBc and delivers a linearity of 1.1:1 across the band.  It comes in Z-COMM's standard USSP package measuring 5.1 x 5.1 x 1.5 mm and is available in tape and reel packaging for production requirements.

The USSP1730-LF is uited for satellite communication applications that require low power consumption as well as low phase noise and extremely small size.
