Anritsu Company announces it has enhanced the LTE measurement capabilities in its MS272xC Spectrum Master™ and MT822xB BTS Master™ series of handheld analyzers. With the new analysis tools added to the existing measurement capabilities, field engineers and technicians have handheld instruments that can conduct nearly all the measurements necessary to successfully deploy, commission, and maintain LTE networks.
The 15C2NX is the RF interface DAS panel that duplexes the BTS port for Rx/UL and Tx/DL channels with the help of a circulator.The power levels on the UL and DL can be adjusted by the use of fixed and manual rotary attenuators. The minimum isolation between channels is 50 dB and with insertion loss of less than 2 dB in the through paths.
This newly designed dual 48 x 4 switch matrix for ATE applications can cover from 700 MHz (LTE) to 6 GHz (Wi-Fi) frequencies. Using high reliability solid state switches, the switching speed is on the order of nanoseconds helping test handsets and other portable communication devices with minimum delay time.
Renaissance Electronics has designed an in-band duplexer for LTE cell site applications. In a very compact footprint of 4.75” x 3.15”, the duplexer provides 30 dB of rejection between the Tx and Rx. The insertion loss is less than 1 dB.
