TBA120 Narrowband FM Receiver -  Here is a nice little receiver for narrow-band FM reception. It can also be used to receive FSK, RTTY and PACKET signals from the HF bands. Basic receiver sensitivity is in the region of 1uV PD and the receiver can be tuned to almost any frequency from 100KHz up to probably 120MHz. Ok then, here is the circuit diagram....

TDA7000 FM Receiver -  (circuit added 08/07/06) 
TDA7000 Receiver -  Philips Semiconductors Application Note 193  In cordless telephone sets, a normal superheterodyne receiver is used for the 1.7MHz handset. The suppression of the adjacent The ceramic IF filter.... [Design by W.V. Dooremolen]
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)

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-frequencyAPP 711: Feb 05, 2001....[App Note]
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)
