UPG2157T5F-A

Product Overview

UPG2157T5F-A is a single-pole double-throw (SPDT) 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 one common RF port switched between two RF paths and operation up to 5.85 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 12-WFQFN Exposed Pad, 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

UPG2157T5F-A can be used in antenna switching, transmit/receive path selection, diversity switching, filter selection and compact RF signal-chain routing. 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.

Quality & Sourcing

Antrex Electronics can support UPG2157T5F-A sourcing with stock availability checks, RFQ quotation, date code review, package confirmation and shipment arrangement. For RF switch purchasing, buyers can provide target quantity, acceptable date code, package requirement, application frequency range and inspection requirements for faster quotation support.

For quality control, Antrex Electronics can help arrange product photos, label review, visual inspection and third-party testing support when required.
