Technical content

Features

  • S21 = 26.3 dB @ 1920 MHz = 24.7 dB @ 2170 MHz
  • NF of 0.95 dB over Frequency
  • Unconditionally Stable
  • Single 5V Supply
  • High OIP3 @ Low Current Note: 1. The number and size of ground via holes in a circuit board is critical for thermal RF grounding considerations. 2. We recommend that the ground via holes be placed on the bottom of all ground pins for better RF and thermal performance, as shown in the drawing at the left side.

6/6 www.asb.co.kr June 2017 plerowTM ALN2045R2 Internally Matched LNA Module 1) The tantal capacitor is optional and for bypassing the AC noise introduced from the DC supply. The capacitance value may be determined by customer’s DC supply status. 2) So-called DC blocking capacitors are always necessarily placed at the input and output port for allowing only the RF s ignal to pass and blocking the DC component in the signal. The DC blocking capacitors are included inside the LNA module. Therefore, C1 & C2 capacitors may not be necessary, but can be added just in case that the customer wants. The value of C1 & C2 is determined by considering the application frequency. Copyright 2007-2017 ASB Inc. All rights reserved. Datasheet subject to change without notice.
