MAX9986A 19-3906 Rev 0 1/06 SiGe High-Linearity, 815MHz to 1000MHz Downconversion Mixer with LO Buffer/Switch General Description Features The MAX9986A high-linearity downconversion mixer 815MHz to 1000MHz RF Frequency Range provides 8.2dB gain, +25dBm IIP3, and 10dB NF for 960MHz to 1180MHz LO Frequency Range 815MHz to 1000MHz base-station receiver applica- (MAX9986A/MAX9986) tions. With a 960MHz to 1180MHz LO frequency range, 570MHz to 850MHz LO Frequency Range this 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 MAX9986A. 8.2dB Conversion Gain +25dBm Input IP3 In addition to offering excellent linearity and noise perfor- mance, the MAX9986A also yields a high level of compo- +14.8dBm Input 1dB Compression Point nent integration. This device includes a double-balanced 10dB Noise Figure passive mixer core, an IF amplifier, a dual-input LO selec- 69dBc 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 MAX9986A requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 250mA. Integrated RF and LO Baluns for Single-Ended Inputs The MAX9986A is a derivative version of the MAX9986 with improved large-signal blocking performance. The Low -3dBm to +3dBm LO Drive MAX9984/MAX9986/MAX9986A are pin compatible with Built-In SPDT LO Switch with 49dB LO1 to LO2 the MAX9994/MAX9996 1700MHz to 3000MHz mixers, Isolation and 50ns Switching Time making this entire family of downconverters ideal for Pin Compatible with MAX9994/MAX9996 1700MHz applications where a common PC board layout is used to 3000MHz Mixers for both frequency bands. The MAX9986A is also func- Functionally Compatible with MAX9993 tionally compatible with the MAX9993. External Current-Setting Resistors Provide Option The MAX9986A is available in a compact, 20-pin, thin for Operating Mixer in Reduced Power/Reduced QFN package (5mm x 5mm) with an exposed paddle. Performance Mode Electrical performance is guaranteed over the extended Lead-Free Package Available -40C to +85C temperature range.
