3.4GHz to 3.8GHz SiGe
Low-Noise Amplifier/PA Predriver
General Description
The MAX2645 is a versatile, high-linearity, low-noise
amplifier designed for 3.4GHz to 3.8GHz wireless local
loop (WLL), wireless broadband access, and digital
microwave radio applications. The device features an
externally adjustable bias control, set with a single resis-
tor, that allows the user to meet minimum linearity require-
ments while minimizing current consumption. The
amplifier ’s high-gain, low-noise performance and
adjustable input third-order intercept (IP3) allow it to be
used as a low-noise amplifier (LNA) in the receive path, a
PA predriver in the transmit path, or as an LO buffer.
The MAX2645 features a logic-level gain control that pro-
vides a 25dB step reduction in gain, which improves IP3
performance for operation during high input signal level
conditions. Supply current is reduced from 9mA in high-
gain mode to 3mA in low-gain mode. The device also
includes a logic-controlled shutdown mode, which
reduces supply current to 0.1μA. The MAX2645 operates
from a +3V to +5.5V supply and is offered in the miniature
10-pin μMAX package (5mm ? 3mm) with an exposed
paddle. Its performance has been optimized for use with
