RF Decibel Meter
In any radio workshop, an RF decibel meter or power meter is an important instrument. Unfortunately, home-constructed ones are generally not sufficiently sensitive and/or are very temperature-dependent. These drawbacks are overcome by a device from Analog Devices which has recently become available: a low-cost DC–500 MHz, 92 dB logarithmic amplif..

Broadband PLL FM Transmitter 88-108 MHz
Here's a simple FM transmitter design. It uses pll circuit from Motorola MC145170. This PLL includes the prescaler and a serial standard bus called SPI. We advise to use the P2 version that fixes some init issues during the Power Up. PLL FM Synthesizer This PLL circuit is definitely smaller than the old one, consequently we've added on the radio ..
