General Description
Functional Diagram
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.
