General Description

The MAX19995A dual-channel downconverter is

designed to provide 8.7dB of conversion gain,

+24.8dBm input IP3, +13.5dBm 1dB input compression

point, and a noise figure of 9.2dB for 1700MHz to

2200MHz diversity receiver applications. With an opti-

mized LO frequency range of 1750MHz to 2700MHz, this

mixer is ideal for high-side LO injection architectures.

Low-side LO injection is supported by the MAX19995,

which is pin-pin and functionally compatible with the

MAX19995A.

In addition to offering excellent linearity and noise per-

formance, the MAX19995A also yields a high level of

component integration. This device includes two double-

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

input LO selectable switch, and a pair of differential IF

output amplifiers. Integrated on-chip baluns allow for sin-

gle-ended RF and LO inputs. The MAX19995A requires a

nominal LO drive of 0dBm and a typical supply current of

350mA at V

= 5.0V, or 242mA at V

= 3.3V.

The MAX19995/MAX19995A are pin compatible with the

MAX19985/MAX19985A series of 700MHz to 1000MHz

mixers and pin similar to 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 MAX19995A 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 (T

= -40°C to +85°C).
