Broadcom Inc. RF Amplifiers ABA-51563-TR1G

The ABA-51563-TR1G is a silicon monolithic broadband RF amplifier designed for applications requiring a frequency range from DC to 3.5 GHz. It features a small-signal gain of 21.5 dB at 2 GHz, with an output P1dB of 1.8 dBm and an output third order intercept point of 11.4 dBm. The amplifier is packaged in a compact SOT-363 package, which occupies half the board space compared to a SOT-143 package, making it suitable for space-constrained designs. This amplifier is optimized for low-cost gain block applications in cellular communications, DBS tuners, and other wireless systems. It operates with a single 5V supply and has a typical current draw of 18 mA. The device is unconditionally stable and exhibits a low noise figure of 3.7 dB, with a voltage standing wave ratio (VSWR) of less than 2.0 across its operating frequency range. The ABA-51563-TR1G is also available in a lead-free option, catering to environmentally conscious designs.
