UPG2189TB-E4-A

Product Overview

UPG2189TB-E4-A is a single-pole single-throw (SPST) RF switch IC from CEL, designed for controlled RF path selection in wireless front ends, microwave signal chains, communication modules and RF test circuitry. It provides single RF path on/off control and operation up to 2.5 GHz, helping designers replace mechanical switching with a compact semiconductor RF switching solution.

For practical design review, this part should be evaluated together with the antenna network, filters, LNA, PA, receiver, transmitter and control logic. The package listed for this orderable code is 6-TSSOP, SC-88, SOT-363, so engineers should compare the land pattern, RF-port orientation, control truth table and assembly requirements with the latest manufacturer datasheet before production approval.

Applications

UPG2189TB-E4-A can be used in RF path enable/disable control, isolation gating, test-loop insertion, receiver protection and antenna-line switching. It is suited to RF front-end designs where signal paths need to be selected electronically while keeping board size, repeatability and switching control under the system controller.

In replacement, repair or BOM-continuation work, buyers should compare the exact topology, frequency range, package footprint, RF-port arrangement and control logic with the original board. Any substitution should also consider loss, isolation, return loss, switching speed, linearity and RF input power limits in the end equipment.
