HMC347LP3 is a high isolation, low insertion loss GaAs MMIC SPDT switch from Hittite, covering DC to 14 GHz. The switch features a QFN package and requires no bias supply.
This datasheet describes the Hittite HMC347LP3, a broadband high isolation non-reflective GaAs MESFET SPDT switch in a low cost leadless QFN surface mount plastic package. The switch covers DC to 14 GHz, offers >50 dB isolation up to 3 GHz and >40 dB isolation up to 13 GHz, and operates from complementary negative control voltage logic lines of -5/0V without a bias supply. It is presented as an alternative to the HMC132C8 SPDT.
The document gives electrical specifications, insertion loss, isolation and return loss curves, input compression and third order intercept plots, a truth table and control voltage table, outline drawing notes and absolute maximum ratings. It also lists pin descriptions with a suggested driver circuit and describes the evaluation PCB (105696) with its list of materials, including SMA connectors, 0603 resistors and Rogers 4350 board material.
