Product Overview
The PF08122B‑TB is a high‑performance dual‑band RF Power Amplifier (PA) module originally designed by Hitachi, later acquired by Renesas. It targets GSM900 and DCS1800 mobile handsets and wireless terminals. This module integrates amplifier stages, internal matching networks and power control circuitry inside compact SMT housing. Operates from single DC supply, delivers high output power, good power‑added efficiency (PAE) for legacy cellular handheld devices.
Core Advantages
Dual‑Band Coverage (GSM900 / DCS1800)
Supports EGSM900 (880‑915 MHz) and DCS1800 (1710‑1785 MHz) within one single module, simplifies dual‑band RF front‑end hardware design.
High Efficiency & Low Power Consumption
Excellent power‑added efficiency reduces battery drain, ideal for battery‑powered portable cellular equipment.
Integrated Matching & Power Control
Built‑in 50 Ohm matching network and power control circuit, reduces external passive components and saves PCB layout space.
Compact SMT Module
Small surface‑mount package, supports automatic pick‑and‑place assembly for mass production.

Frequently Asked Questions
Q1: What frequency bands are supported by the PF08122B‑TB?
A: It supports dual‑band EGSM900 (880‑915 MHz) and DCS1800 (1710‑1785 MHz) mobile communication.
Q2: Does PF08122B‑TB need external RF matching components?
A: It has built‑in 50‑Ohm matching network. Only a small number of external passive parts are needed for operation.
Q3: What does “-TB” suffix mean for PF08122B‑TB?
A: “-TB” refers to tape‑and‑reel packaging for SMT assembly. PF08122B is bare component; TB stands for reel packing.
Q4: Is PF08122B‑TB still in production?
A: This legacy GSM power amplifier is obsolete. Stock is surplus inventory, not suggested for new mass‑production projects.
Q5: Are there compatible alternatives for PF08122B‑TB?
A: No direct pin‑to‑pin replacement is available. New GSM PA modules require PCB redesign for migration.
Q6: How to get datasheet, pinout info or bulk price?
A: Submit quick inquiry for official datasheets, CAD files, stock status and volume quotation. We reply within 24 hours.
