HMC322LP4

GaAs MMIC SP8T NON-REFLECTIVE

SWITCH, DC - 8.0 GHz

v03.0604

General Description

Features

Functional Diagram

The HMC322LP4 is a broadband non-reflective

GaAs MESFET SP8T switch in a low cost lead-

less surface mount package. Covering DC to 8

GHz, this switch offers high isolation and low

insertion loss. This switch also includes an on

board binary decoder circuit which reduces the

required logic control lines to three. The switch

operates using a negative control voltage of 0/-5

volts, and requires a fixed bias of -5v. This switch

is suitable for usage in 50-Ohm or 75-Ohm sys-

tems.

Broadband Performance: DC - 8.0 GHz

High Isolation: >30 dB@ 6 GHz

Low Insertion Loss: 2.4 dB@ 6 GHz

Integrated 3:8 TTL Decoder

4 mm x 4 mm x 1 mm SMT Package

Typical Applications

This switch is suitable for usage in DC - 8.0 GHz

50-Ohm or 75-Ohm systems:

• Broadband

• Fiber Optics

• Switched Filter Banks

• Wireless below 8 GHz
