+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 ±1dB variation over supply, temperature, and input power.
With two optional resistors, the output power can be precision set from +14dBm to +20dBm.
The devices offer more than 35dB main driv...
