Demodulating with the LMX2240 150 MHz IF Receiver
ثبت نشده
چکیده
The applications for the LMX2240 IF Receiver are discussed. Practical limitations of high frequency IF demodulators are examined, and methods to cope with these limitations are introduced. Specifically, methods to reduce the susceptibility to oscillation are given, and include layout considerations as well as circuit implementations. In addition, the demodulator tank circuit is examined in detail, and three configurations for the tank circuit are given. Theoretical derivations and plots for the tank circuits are presented, as well as measured results. The measured results agree well with the theoretical predictions.

متن کاملDual-Frequency and Multi-Receiver Radars for Sounding and Imaging Polar Ice Sheets
We developed radars for operation at 150 MHz with a bandwidth of 20 MHz and 450 MHz with a bandwidth of 30 MHz with multiple receivers for sounding and imaging polar ice sheets. The system consists of six receivers used to collect and digitize signals from each element of an antenna array. The antennas consisted of two fourelement dipole-arrays mounted under each wing of a NASA P-3 aircraft. We...

A novel RF-optical receiver architecture based on nonlinear optical modulation in a LiNbO3 microdisk modulator is presented. This is the first RF-optical receiver without high-speed electronic components for transmitted carrier links. We demonstrate receiver operation by demodulating 50 Mb/s digital data from a 8.7 GHz carrier frequency. 2005 Elsevier Ltd. All rights reserved.
متن کاملThe 1024 channel digital correlator receiver of the Gauribidanur radioheliograph
A low frequency (40–150 MHz) radioheliograph for observations of the solar corona is in operation for the last few years at the Gauribidanur radio observatory, about 100 km north of Bangalore. The array has 32 antenna groups and a 1-bit digital correlator system consisting of 1024 channels is used as the back-end receiver. This paper describes the latter and results of the associated system tests.
