GENERAL DESCRIPTION
The
HMC1161
is a monolithic microwave integrated circuit
(MMIC), voltage controlled oscillator (VCO) that integrates a
resonator, a negative resistance device, and a varactor diode,
and features a half frequency output.
Because of the monolithic construction of the oscillator, the
output power and phase noise performance are excellent over
temperature.
The output power is 11 dBm typical from a 5 V supply voltage.
The VCO is housed in a RoHS-compliant LFCSP and requires
no external matching components.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
