UPG2181T5R-E2-A の詳細説明
Product Overview
UPG2181T5R-E2-A is a 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 controlled RF path selection and operation up to 3.8 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 20-UFQFN 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.
Key Features
- Manufacturer: CEL
- Part Number: UPG2181T5R-E2-A
- Device Type: RF switch IC
- RF Frequency Range: up to 3.8 GHz
- RF Path Function: controlled RF path selection
- Technology / Construction: RF semiconductor switch IC for compact wireless front-end signal routing
- System Impedance: 50 Ω RF signal-path design reference where supported by the datasheet
- Package / Case: 20-UFQFN Exposed Pad
- Assembly Consideration: Surface-mount package for compact RF PCB layouts
- Use Case: antenna switching, transmit/receive routing or RF signal-chain path selection
- Design Notes: Verify insertion loss, isolation, return loss, switching speed, RF power handling, bias/control limits and pinout against the official datasheet before final approval.
Applications
UPG2181T5R-E2-A can be used in antenna switching, transmit/receive path selection, diversity switching, filter-bank routing, test-port selection and configurable RF front-end designs. 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 UPG2181T5R-E2-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. OEMs, EMS providers, RF module manufacturers, communication-equipment builders, repair teams and electronic component buyers are welcome to send BOM lists or hard-to-find RF switch requests for sourcing assistance.
