MAX19995 19-4253 Rev 0 12/08 Dual, SiGe, High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch General Description Features The MAX19995 dual-channel downconverter provides 1700MHz to 2200MHz RF Frequency Range 9dB of conversion gain, +24.8dBm input IP3, 1400MHz to 2000MHz LO Frequency Range +13.3dBm 1dB input compression point, and a noise figure as low as 9dB for 1700MHz to 2200MHz diversity 1750MHz to 2700MHz LO Frequency Range receiver applications. With an optimized LO frequency (MAX19995A) range of 1400MHz to 2000MHz, this mixer is ideal for 50MHz to 500MHz IF Frequency Range low-side LO injection architectures. High-side LO injec- tion is supported by the MAX19995A, which is pin-pin 9dB Typical Conversion Gain and functionally compatible with the MAX19995. 9dB Typical Noise Figure In addition to offering excellent linearity and noise per- +24.8dBm Typical Input IP3 formance, the MAX19995 also yields a high level of component integration. This device includes two dou- +13.3dBm Typical Input 1dB Compression Point ble-balanced passive mixer cores, two LO buffers, a 79dBc Typical 2RF-2LO Spurious Rejection at dual-input LO selectable switch, and a pair of differen- P = -10dBm RF tial IF output amplifiers. Integrated on-chip baluns allow for single-ended RF and LO inputs. Dual Channels Ideal for Diversity Receiver Applications The MAX19995 requires a nominal LO drive of 0dBm and a typical supply current of 297mA at V = 5.0V or CC 49dB Typical Channel-to-Channel Isolation 212mA at V = 3.3V. CC Low -3dBm to +3dBm LO Drive The MAX19995/MAX19995A are pin compatible with Integrated LO Buffer the MAX19985/MAX19985A series of 700MHz to 1000MHz mixers and pin similar with the MAX19997A/ Internal RF and LO Baluns for Single-Ended MAX19999 series of 1800MHz to 4000MHz mixers, Inputs making this entire family of downconverters ideal for Built-In SPDT LO Switch with 56dB LO-to-LO applications where a common PCB layout is used Isolation and 50ns Switching Time across multiple frequency bands. The MAX19995 is available in a 6mm x 6mm, 36-pin Pin Compatible with the MAX19985/MAX19985A/ thin QFN package with an exposed pad.

This formula can be used when the temperature of the exposed J C JC CC CC pad is known while the device is soldered down to a PCB. See the Applications Information section for details. The junction temperature must not exceed +150C. Note 2: Junction temperature T = T + ( x V x I ). This formula can be used when the ambient temperature of the PCB is J A JA CC CC known. The junction temperature must not exceed +150C. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four- layer board.
