3.4GHz to 3.8GHz SiGe  
Low-Noise Amplifier/PA Predriver  
General Description  
Features  
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.

Transmit PA Predriver  
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
