The MAX19995 dual-channel downconverter provides

up to 9dB of conversion gain, +24.8dBm input IP3,

+13.3dBm 1dB input compression point, and a noise

figure as low as 9dB for 1700MHz to 2200MHz diversity

receiver applications. With an optimized LO frequency

range of 1400MHz to 2000MHz, this mixer is ideal for

low-side LO injection architectures. High-side LO injec-

tion is supported by the MAX19995A, which is pin-pin

and functionally compatible with the MAX19995.

In addition to offering excellent linearity and noise per-

formance, the MAX19995 also yields a high level of

component integration. This device includes two dou-

ble-balanced passive mixer cores, two LO buffers, a

dual-input LO selectable switch, and a pair of differen-

tial IF output amplifiers. Integrated on-chip baluns allow

for single-ended RF and LO inputs.

The MAX19995 requires a nominal LO drive of 0dBm

and a typical supply current of 297mA at V

212mA at V

The MAX19995/MAX19995A are pin compatible with

the MAX19985/MAX19985A series of 700MHz to

1000MHz mixers and pin similar with the MAX19997A/

MAX19999 series of 1800MHz to 4000MHz mixers,

making this entire family of downconverters ideal for

applications where a common PCB layout is used

across multiple frequency bands.

The MAX19995 is available in a 6mm x 6mm, 36-pin

thin QFN package with an exposed pad. Electrical per-

formance is guaranteed over the extended temperature

range, from T
