Key Features

The HMC344ALP3E from Analog Devices is a non-reflective single-pole, four-throw (SP4T) RF switch that supports broadband frequencies from 0.1 GHz to 8 GHz. Engineered using gallium arsenide MESFET technology, it delivers low insertion loss of 1.7 dB and high isolation of 36 dB at 6 GHz. Its integrated 2-bit binary decoder allows control with just two logic inputs, which simplifies board design and reduces system complexity. The component supports high input power levels with a P1dB of 28 dBm and a typical IP3 of 44 dBm. Thus making it suitable for high-performance RF applications. Its compact 16-lead LFCSP package fits efficiently into dense circuit layouts while maintaining mechanical stability and thermal reliability.

Applications

Broadband telecom infrastructure using RF path switching in the 0.1 to 8 GHz range
Microwave radios in backhaul networks using frequency band switching
Switched filter banks in spectrum analyzers and test instruments
Signal path routing in optical transceivers for fiber network modulation
Advanced radar systems requiring fast, high-isolation RF channel switching

Product Overview

Analog Devices’ HMC344ALP3E is a high-frequency RF switch designed to support multiple signal routing needs in broadband systems. Its GaAs design ensures fast switching performance and high linearity, ideal for sensitive RF and microwave applications. Because the switch is non-reflective, it absorbs rather than reflects unused paths. This protects sensitive downstream components and enhances circuit performance. Its integrated logic decoder reduces the number of required GPIO lines in embedded systems. With proven performance up to 8 GHz, this switch finds use in critical applications such as military-grade radar systems, precision laboratory instrumentation, and 5G infrastructure. It operates reliably across extended temperatures and meets RoHS compliance for environmental safety.
