Functional Diagram
General Description
The HMC-C073 is a high performance VCO that operates over a 38.4 to 43.2 GHz band. An internal output buffer provides +13 dBm of output power and provides excellent frequency pulling performance. Phase noise is excellent at -98 dBc/Hz at 100 kHz offset and the unit provides exceptionally low jitter of 37 fs (calculated). The Vtune port accepts an analog tuning voltage from +2 to +13V. This robust VCO is housed in a very small hermetic module measuring 0.7” x 0.99” x 0.23”. The module is supplied with a 2.4mm connector, which can be replaced by a GPO connector.
