TQP4M0008

Overview

The TQP4M0008 is a GaAs FET single-pole, double-throw (SPDT) reflective RF switch designed for broadband applications. It operates from 100 MHz to 6 GHz with a compact 6-pin 2x2 mm surface-mount leadless package. Key electrical parameters include an insertion loss of 0.85 dB at 6 GHz, typical off-isolation of 17 dB, and a P1dB compression point of 37 dBm. The input third-order intercept point (IIP3) is 56 dBm. It supports 50-ohm impedance and functions within a temperature range of -40°C to 95°C.

Feature Summary

• Utilizes GaAs FET technology for low-loss signal switching in broadband RF paths.
• Reflective SPDT topology suitable for cellular, WLAN, and VHF/UHF systems.
• Compact 2x2 mm leadless surface-mount package for space-constrained designs.

Applications

• Cellular infrastructure and handsets
• Wireless LAN (WLAN) modules
• VHF/UHF radio equipment

Procurement Notes

Verify the specific ordering suffix required for tape-and-reel or cut-tape quantities against manufacturer specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements for your assembly process. Ensure the selected variant matches the intended frequency range and power handling needs for your specific RF application design.

Selection Notes

Select this component when a low-insertion-loss SPDT switch is needed across the 100 MHz to 6 GHz spectrum. The high IIP3 and P1dB values make it suitable for linear signal routing in multi-band transceivers. Consider the 2x2 mm footprint for PCB layout constraints compared to larger packages offering similar performance metrics.
