General Description
The HMC204MS8G is a passive miniature frequency doubler in an 8 lead MSOP surface
mount package. Suppression of undesired fundamental and higher order harmonics is 40 to 60
dB with respect to input signal level and 24 to 42
dB with respect to the output level. The doubler
utilizes the same GaAs Schottky diode/balun
technology found in Hittite MMIC mixers. Its
features includes a small size, requires no DC
bias, and has no measurable additive phase
noise onto the multiplied signal. Applications
include commercial microwave radios and VSAT,
as well as military ECM and communication
systems.
Guaranteed Perf ormance, 50 Ohm system -55 to +85 deg C
