Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
PIC16F84 RF remote Controller -  With a handful of inexpensive components, a little creativity, and the power of PicBasic, you can build some pretty outstanding robotics creations as Rob Arnold proves with his Ruf-Bot project… [Rob Arnold]
Popcorn direct Conversion receiver -  schematic for a no-frills, relatively low-cost CW superhet receiver with a 4.00 MHz Intermediate frequency. There is no AGC or RF gain control, however this receiver has good large signal handling capability.  This receiver uses just 6 bipolar transistors and an op amp for reasonable volume into headphones. Much....(design added 05/08)
Precision 300MHzto 7GHz RF Detector with Gain & Offset Adjustment -  Linear Technology LTC5509....[App Note]
Precision 300MHzto 7GHz RF Detector with Shutdown & Gain Adjustment -  Linear Technology LTC5530....[App Note]
Precision 600 MHz to 7GHz RF Detector with Adjustable Gain & 12MHz Baseband Bandwidth -  Linear Technology LT5534....[App Note]

Program predicts VSWR mismatch RF uncertainties -  02/01/01 EDN-Design Ideas....Hewlett-Packard (now Agilent Technologies] once offered a useful little cardboard slide rule for calculating the uncertainty in RF  measurements stemming.... [Design Idea by Steve Hageman, Agilent Technologies, Santa Rosa, CA]
R/C Switch -  This circuit is a so-called "Radio controlled Electronic Switch". It can be used to switch on/off anything electrical, whatever it is. Here are a couple of examples: navigation lights, landing gear, sound systems, Glowplug driver, bomb release, parachute, search lights, gyros, and so on.  This circuits connects to a RC car controller servo output….. [Tony van Roon's circuit]
