TBA120 Narrowband FM Receiver - (circuit design added 8/03)
TDA7000 FM Receiver - (circuit added 08/07/06)
TDA7000 Receiver - (circuit design added 8/03)
TDA7088 Receiver - Site has annoying popups.  The electronic diagram of the monophonic FM receiver made with TDA7088T is shown on Pic.4.12. If built with SMD components it can be placed in a matchbox, altogether with two button-type batteries. The operating principle of this device is given in the...(circuit added 08/07/06)
The "UnFETtered Crystal Radio! - ….(circuit design added 08/08)
The MRX 40 Mini Receiver - (circuit design added 8/03)

TL431 Crystal Radio Amplifier - Here is a simple audio amplifier using a TL431 shunt regulator. The amplifier will provide room-filling volume from an ordinary crystal radio outfitted with a long-wire antenna and good ground. The circuitry is similar in complexity to a simple one-transistor radio but the performance is far superior. The TL431….(added 04/05/06)
Trimless IF VCO: Part 1: Design Considerations - This App Note explores the design fundamentals needed to implement a trimless, fixed-frequency, IF voltage-controlled oscillator (VCO) and points out the challenges in guaranteeing proper circuit operation. VCOs are essential components in the architecture of most wireless systems. In dual-conversion approaches, a fixed-frequency....  APP 711: Feb 05, 2001  (app note added 02/05)
Tunable IF with TDA7000 - The main motive of the mods was not that the circuit didn't work right, but were several tries to add some kind of frequency indicator to the receiver. The left RCA plug and associated components are witnesses to the last version, adding a FET buffer amplifiera and taking signal from the oscillator coil. (added 02/05)
Two-band radio - ….(circuit design added 03/08)
UltraLow Distortion IF Amplifier/ ADC Driver with Digitally Controlled Gain - Linear Technology LT5514 (app note added 02/05)
Using the MCP2150 to Add IRDA® Standard Wireless Connectivity - Microchip Application Note Published 4-Jun-01   (app note added 2/06)
Using the PIC16f639 Mcu for Smart Wireless Applications - Microchip Application Note Published 10-Nov-04   (app note added 6/06)
