Data Sheet

July 1998

File Number 4132.4

2.4GHz - 2.5GHz 250mW Power Ampliﬁer

Features

• Highly Integrated Power Ampliﬁer with T/R Switch

• Operates Over 2.7V to 6V Supply Voltage

signaling. The HFA3925 2.4GHz-

2.5GHz, 250mW power ampliﬁer is one of the ﬁve chips in

the PRISM™ chip set (see the Typical Application Diagram).

• Individual Gate Control for Each Ampliﬁer Stage

• Low Cost SSOP-28 Plastic Package

The Intersil HFA3925 is an integrated power ampliﬁer with

transmit/receive switch in a low cost SSOP 28 plastic

package. The power ampliﬁer delivers +27dB of gain with

high efﬁciency and can be operated with voltages as low as

2.7V. The power ampliﬁer switch is fully monolithic and can

be controlled with CMOS logic levels.

Applications

• Systems Targeting IEEE 802.11 Standard

• TDD Quadrature-Modulated Communication Systems

• Wireless Local Area Networks

• PCMCIA Wireless Transceivers

• ISM Systems

The HFA3925 is ideally suited for QPSK, BPSK or other

linearly modulated systems in the 2.4GHz Industrial,

Scientiﬁc, and Medical (ISM) frequency band. It can also be

used in GFSK systems where levels of +25dBm are

required. Typical applications include Wireless Local Area

Network (WLAN) and wireless portable data collection.

• TDMA Packet Protocol Radios

• PCS/Wireless PBX
