Crystek has released the company's
CVCO55FLM-0137-0171 which operates from 137 MHz to 171 MHz with a
control voltage range of 0.5 V to 4.5 V. The VCO (Voltage Controlled
Oscillator) features a typical phase noise of -118 dBc/Hz at 10 KHz
offset and claims to have excellent linearity.
Crystek's CVCO55FLM VCOs contain an extra modulation port
(TX modulation), making the family an ideal choice for transmitter
applications. The modulation port has a negative slope and a typical
modulation sensitivity of -25 KHz/V.
The model CVCO55FLM-0137-0171 is packaged in the industry-standard
0.5-inch x 0.5-inch SMD package. Output power is typically 0 dBm, and
input voltage is 5 V, with a max. current consumption of 20 mA. Pulling
and Pushing are minimized to 1.5 MHz and 0.5 MHz/V, respectively. Second
harmonic suppression is -15 dBc typical.
