Intersil HFA3925
The HFA3925 2.4GHz2.5GHz, 250mW power amplifier is one of the five chips in the PRISM™ chip set (see the Typical Application Diagram). 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.| Part No. | HFA3925 |

FEATURES
● Highly Integrated Power Amplifier with T/R Switch● Operates Over 2.7V to 6V Supply Voltage
● High Linear Output Power (P1dB: +24dBm)
● 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 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. 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 HFA3925 Power Amplifier.
