MAXIM MAX9987/MAX9988 handbook

Update: 30 September, 2023

MAX9987/MAX9988 is a MAXIM's RF transceiver. The device integrates a passive two-way power splitter with high-isolation input and output buffer amplifiers. These buffers are designed to provide the high output (+14dBm to +20dBm) necessary to drive the LO inputs of high-linearity passive mixers, while offering 40dB reverse isolation to prevent LO pulling. The MAX9987 is internally matched for the cellular/GSM bands, and the MAX9988 is matched for the DCS/PCS/UMTS bands. The typical application circuit provides a nominal +17dBm output power with ±1dB variation over supply, temperature, and input power. With two optional resis- tors, the output power can be precision set from +14dBm to +20dBm. The devices offer more than 30dB output-to-output port isolation, and are offered in 5mm ✕ 5mm 20-pin thin QFN packages with exposed paddle.
