MAX9995_13 Datasheet, PDF (1/13 Pages) Maxim Integrated Products – Dual, SiGe, High-Linearity, 1700MHz to 2700MHz Downconversion Mixer with LO Buffer/Switch

EVALUATION KIT AVAILABLE
MAX9995
Dual, SiGe, High-Linearity, 1700MHz to 2700MHz
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX9995 dual, high-linearity, downconversion
mixer provides 6.1dB gain, +25.6dBm IIP3, and 9.8dB
NF for WCDMA, TD-SCDMA, LTE, TD-LTE, and
GSM/EDGE base-station applications.
This device integrates baluns in the RF and LO ports, a
dual-input LO selectable switch, an LO buffer, two double-
balanced mixers, and a pair of differential IF output ampli-
fiers. The MAX9995 requires a typical LO drive of 0dBm
and supply current is guaranteed to be below 380mA.
These devices are available in a compact 36-pin TQFN
package (6mm × 6mm) with an exposed pad. Electrical
performance is guaranteed over the extended tempera-
ture range, from T_C = -40°C to +100°C.
