GENERAL DESCRIPTION
The HMC641A is a nonreflective, single-pole, four-throw
(SP4T) switch, manufactured using a gallium arsenide (GaAs)
process. This switch typically provides low insertion loss of
2.1 dB and high isolation of 42 dB in broadband frequency
range from 0.1 GHz to 18 GHz.
The HMC641A includes an on-chip, binary 2 to 4 line decoder
that provides control from two logic input lines.
The switch operates with a negative supply voltage of −5 V to
−3 V and requires two negative logic control voltages.
All electrical performance data is acquired with the HMC641A
that all RFx pads are connected to by the 50 Ω transmission
lines via one 3.0 mil × 0.5 mil ribbon bond of minimal length.
