Low-Cost RF Up/Downc onverter

_______________Detailed Desc ription
The MAX2410 consists of five major components: a
transmit mixer, a variable-gain power-amplifier (PA)
driver, a low-noise amplifier (LNA), a receive mixer, and
power-management section.
The following sections describe each block in the
MAX2410 Functional Diagram
Low-Noise Amplifier (LNA)
The LNA is a wideband, single-ended cascode amplifi-
er that can be used over a wide range of frequencies
(refer to the LNA Gain vs. Frequency graph in the
Typical Operating Characteristics). Its port impedances
are optimized for operation around 1.9GHz, requiring
only a 1pF shunt capacitor at the LNA input for a VSWR
of better than 2:1 and a noise figure of 2.4dB. As with
every LNA, the input match can be traded off for better
noise figure.
