APPLICATIONS INFORMATION

The HMC1163 serves as the local oscillator (LO) in microwave

synthesizer applications. The primary applications are point to

point microwave radios, military, radars, test and measurement,

as well as industrial and medical equipment. The low phase

noise allows higher orders of modulation and offers improved bit

error rates in communication systems, whereas the linear,

monotonic tuning sensitivity allows a stable loop filter design. The

higher output power minimizes the gain required to drive

subsequent stages. The half frequency output reduces the input

frequency to the prescaler without the addition of residual

phase noise to the input of the phase-locked loop synthesizer.
