General Description
The HMC7447 is a high performance E-Band MMIC
power detector designed to operate over the 71 to 86
GHz frequency range. The power detector provides a
linear output voltage over a -0.5 to +23.5 dBm input
power range with low insertion loss of 0.45 dB and
typical input return loss of only 19.5 dB. Ideal for
monitoring transmitter operation or enabling closed-
loop transmitter output power, the detector exhibits
excellent sensitivity and flat frequency response of
+/- 0.2 dB over the 71 to 76 GHz band and the 81
to 86 GHz band. The HMC7447 power detector also
provides excellent repeatabillity and performance over
varying temperature and output load variations. It may
be interfaced to an op-amp circuit to achieve a slope of
20 mV/dB at the minimum detector input power level.
All data is taken with the chip in a 50 Ohm test fixture
connected via a 0.025 mm (1mil) diameter double wire
bonds of 0.2 mm (8 mils) maximum length.
