Demodulating Receiver
The Demodulating Receiver (A3017) features a 902 to 930 MHz 30-dB amplifier, a downshifter, a 60-dB 50-MHz limiting IF amplifier, a frequency discriminator, and an amplitude demodulator. The A301701A circuit board also includes additional copies of the A3016SO SAW Oscillator...
optimized 6 element uhf yagi antenna
The diameter of the antenna elements can range from 5.8 mm, while the dipole diameter can vary from 8 mm to 12 mm, with 12 mm being the recommended size. This adjustment can be made without altering the length or...
Jammer circuit
The frequency jammer operates by generating interfering RF noise centered around a 2.45 GHz carrier frequency. As the power of this noise increases, the signal-to-noise ratio of the wireless communication channel decreases, leading to a higher bit error rate until...

REGENERATIVE_SHORTWAVE_RECEIVER
The receiver consists of multiple subassemblies, including an active antenna, an amplifier featuring regeneration control and band-switching circuitry, an AM detector, a power amplifier, and an output device such as an internal speaker, external speaker, or headphones. Additionally, it is...
2 channel RF remote control
The basic small-range remote controls are Infrared and RF (Radio Frequency). One of the weaknesses of Infrared is that the signal cannot pass through walls. Therefore, to control a garage door, an RF remote control is necessary. The circuit (transmitter...
