Overview
ARAFTEK , INC.
AR7241A PRELIMINARY 2.
4GHz ISM Band MMIC LNA Features • 2.
3 dB Noise Figure • 24 dB Gain • Single-Supply Bias • 8L-SOP Plastic package with ground slug for low-inductance RF grounding • Analog Gain Control with positive voltage • Input /Output 50 Ω matched Applications • ISM-Band spread-spectrum wireless communications • Wireless Local Area Networks • Wireless Data Terminals • Wireless Remote Monitoring The AR7241A is a fully matched three-stage, single-supply monolithic LNA designed for wireless applications in the 2.
4 - 2.
5 GHz ISM band.
Bias, DC blocking and matching circuitry is included on-chip allowing for easy implementation.
Optional analog gain control pin is provided for AGC function.
The small-sized 8-pin SOP package is ideal for PCMCIA card applications.
AR7241A reduces development time and cost of developing 2.
4 GHz RF subsystems.
