- (MAX9989 / MAX9990) +14dBm to +20dBm LO Buffers - Buffer
19-2486; Rev 0; 7, 02 +14dBm to +20dBm LO Buffers with ±1dB Variation General Description The MAX9989 and MAX9990 LO buffers 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 MAX9989 is internally matched for the cellular, GSM bands, and the MAX9990 is matched for the DCS, PCS, UMTS bands. The Typical Application Circuit provides a nominal +17dBm output power with ±1d
