Description

The SPA-2118 is a high efficiency GaAs Heterojunction Bipolar Transistor (HBT) amplifier housed in a low-cost surface-mountable plastic package. These HBT amplifiers are fabricated using molecular beam epitaxial growth technology which produces reliable and consistent performance from wafer to wafer and lot to lot.

Features of the SPA-2118 are:(1)high linearity performance:+20.7 dBm  IS-95 CDMA channel power at -55 dBc ACP,+47 dBm typ. OIP3; (2)on-chip active bias control; (3)high gain:  33 dB typ.; (4)patented high reliability GaAsHBT technology; (5)surface-mountable plastic package.This product is specifically designed for use as a driver amplifier for infrastructure equipment in the 850 MHz band.Its high linearity makes it an ideal choice for multi-carrier and digital applications.

The absolute maximum ratings of the SPA-2118 can be summarized as:(1)Max. device  voltage:6 V;(2)supply current:150mA;(3)junction temperature range:160;(4)storage temperature:150;(5)max. RF input power:10 dB.Bias should be supplied to this pin through an external RF choke. Because DC biasing is present onthis pin, a DC blocking capacitor should be used inmost applications (see applicationschematic). The supply side of the bias network should be well bypassed. Anoutput matching network is necessary for optimum performance.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
