GENERAL DESCRIPTION

The HMC7992 is a general-purpose, nonreflective, 0.1 GHz to

6.0 GHz, silicon, single-pole, four-throw (SP4T) switch in a

leadless, surface-mount package. The switch is ideal for cellular

infrastructure applications, offers high isolation of 45 dB typical

at 2 GHz, and a low insertion loss of 0.6 dB at 2 GHz. It offers

excellent power handling capability up to 6.0 GHz, with input

power of 1 dB compression point (P1dB) of 35 dBm at 5 V

operation. The HMC7992 has good low frequency input power

handling below 0.1 GHz and can operate well down to 10 kHz,

with a typical 1 dB compression of 21 dBm (see Figure 21) and

an IIP3 of 37 dBm (see Figure 22) at 1 MHz.

The on-chip circuitry allows the HMC7992 to operate at a single,

positive supply voltage range from 3.3 V to 5 V, and as well as a

single, positive control voltage from 0 V to 1.8 V/3.3 V/5.0 V. A

2:4 decoder integrated in the switch requires only two controlled

input signals, with a positive control voltage range from 0 V to

1.8 V/3.3 V/5.0 V, to select one of the four radio frequency (RF)

paths.
