MSA-2111-TR1 [Broadcom]

The MSA-2111 is a cascadable 50Ω gain block MMIC amplifier fabricated using Agilent’s silicon bipolar process. It features medium output power (10 dBm at 900 MHz), high gain (16.5 dB typical at 900 MHz), and low noise figure (3.3 dB typical at 900 MHz). The device uses an external bias resistor for temperature and current stability, offering bias flexibility. It is housed in a low-cost surface-mount plastic SOT-143 package and is available in tape-and-reel packaging with lead-free options.
