GaAs, Nonreflective, SP4T Switch 100 MHz to 4 GHz

The HMC241ALP3E is a general-purpose, nonreflective, 100 MHz to 4 GHz single-pole, four-throw (SP4T) switch manufactured using a gallium arsenide (GaAs) process. This switch offers high isolation of 43 dB typical at 2 GHz, low insertion loss of 0.7 dB at 2 GHz, and on-chip termination of the isolated ports.

The on-chip circuitry allows the HMC241ALP3E to operate at a single, positive supply voltage range of 3 V to 5 V. This switch requires two positive logic control voltages. The HMC241ALP3E includes an on-chip, binary two to four line decoder that provides logic control from two logic input lines to select one of the four radio frequency (RF) lines.

The HMC241ALP3E is available in a 3 mm × 3 mm, 16-lead LFCSP package. The HMC7992 is the silicon version of this switch and features better performance up to higher frequencies.
