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.
