HFA3926 Datasheet | Intersil

Features - Highly Integrated Power Amplifier - Operates Over 2.7V to 6V Supply Voltage - High Linear Output Power (P1d B: +24.5d Bm) - Low Cost SSOP-28 Plastic Package The HFA3926 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 +25d Bm are required. Typical applications include Wireless Local Area Network (WLAN) and Wireless Local Loop systems. REMEMBER: Always apply Negative power to the VG pins before applying the Positive VDD bias. Failure to do so may result in the destruction of the HFA3926 Power Amplifier. Applications - Wireless Local Loop Systems - Systems Targeting IEEE 802.11 Standard - TDD Quadrature-Modulated munication Systems - Wireless Local Area Networks - PCMCIA Wireless Transceivers - ISM Systems Ordering Information PART NUMBER HFA3926IA HFA3926IA96 TEMP.
