ADA-4543-TR1

RF Amplifiers Overview

The ADA-4543-TR1 is a single-channel RF amplifier manufactured by Broadcom Limited, designed for mobile phone, PCS, WLL, and WLAN applications. It operates within a frequency range of 0Hz to 2.5GHz, tested at 900MHz. The device provides a gain of 15.1dB with a noise figure of 3.7dB and a P1dB compression point of 1.9dBm. It requires a supply voltage of 3.1V to 3.8V and draws a supply current of 15mA. Packaged in an SOT-343 (SC-82A) surface-mount case, this silicon-based component is currently obsolete and no longer in production.
