MAX9986 19-3605 Rev 0 2/05 SiGe High-Linearity, 815MHz to 995MHz Downconversion Mixer with LO Buffer/Switch General Description Features The MAX9986 high-linearity downconversion mixer pro- 815MHz to 995MHz RF Frequency Range vides 10dB gain, +23.6dBm IIP3, and 9.3dB NF for 960MHz to 1180MHz LO Frequency Range 815MHz to 995MHz base-station receiver applications. (MAX9986) With a 960MHz to 1180MHz LO frequency range, this 570MHz to 850MHz LO Frequency Range particular mixer is ideal for high-side LO injection (MAX9984) receiver architectures. Low-side LO injection is sup- 50MHz to 250MHz IF Frequency Range ported by the MAX9984, which is pin-for-pin and func- tionally compatible with the MAX9986. 10dB Conversion Gain +23.6dBm Input IP3 In addition to offering excellent linearity and noise perfor- mance, the MAX9986 also yields a high level of compo- +12dBm Input 1dB Compression Point nent integration. This device includes a double-balanced 9.3dB Noise Figure passive mixer core, an IF amplifier, a dual-input LO selec- 67dBc 2LO-2RF Spurious Rejection at table switch, and an LO buffer. On-chip baluns are also P = -10dBm RF integrated to allow for single-ended RF and LO inputs. Integrated LO Buffer The MAX9986 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 265mA. Integrated RF and LO Baluns for Single-Ended Inputs The MAX9984/MAX9986 are pin compatible with the MAX9994/MAX9996 1700MHz to 2200MHz mixers, Low -3dBm to +3dBm LO Drive making this entire family of downconverters ideal for Built-In SPDT LO Switch with 49dB LO1 to LO2 applications where a common PC board layout is used Isolation and 50ns Switching Time for both frequency bands.
