General Description
The HMC986A is a wideband GaAs pHEMT MMIC
Single Pole Double Throw (SPDT) switch die. This tiny
switch employs a reective topology and is controlled
with two complementary inputs of 0/-3V to 0/-5V. With
an input signal at 40 GHz, the HMC986A exhibits 19 dB
return loss, 34 dB isolation, and only 2.1 dB insertion
loss. The combination of wideband performance and
fast switching speed make this switch ideal for test
equipment, switching matrices, and electronic warfare
(EW) applications. RF performance is independent of
high level control voltages, and is shown at both -3V
and -5V for completeness.
Wideband Performance: 0.1 to 50 GHz
Low Insertion Loss: 2.1 dB at 40 GHz
High Isolation: 34 dB at 40 GHz
Fast Switching Speed: 11 ns
Compact Die Size: 0.98 x 0.75 x 0.1 mm
