- Single Supply The ALN 1730WB is the compactly designed su rface- mount internally matched LNA module for the use in the infrastructure equipment of the mobile wireless ( LTE, GSM, PCS, WCDMA, WLAN, WiBro, WiMAX ) a nd so on. It has an exceptional performance of low noise fi g- ure, high gain, high OIP3, and low bias current from 1700MHz to 3 500MHz fr equency band . The surface - mount module package including the completed matc h- ing circuit and other components necessary just in case allows very simple and conve nient implementation onto the system board in mass production level.

The ca pacitance value may be determined by customer ’s DC supply status . The c apacitor should be placed as close as possible to Vs pin and be connected direc tly to the ground plane for the best electrical performance . 2) DC blocking capacitors are alw ays necessarily placed at the input and output port for allowing only the RF signal to pass and blockin g the DC component in the signal. The DC blocking capacitors are included inside the ALN module. Therefore, C1 & C2 capacitor s may not be necessary, but can be added just in case that the customer wants. The value of C1 & C2 is determined by considering t he application fr equency. Copyright 2013-2017 ASB Inc. All rights reserved. Datasheet subject to change without notice.
