The following circuit is a UHF RECEIVER at 433Mhz using the RF290/433 from Aurel (www.aurel.it). The receiver circuit uses an LM741 and a LM386. The transient and AC analysis of the amplifier were simulated using ICAP/4 from Intusoft (www.intusoft.com). This is a spice package and results of the circuit are shown below. The DC voltage used is 9VDC. Setting the pot half way will result in an output power of 22mW. One can adjust the pot for maximum gain.
