50W Tube-Valve SW transmitter
This transmitter operates in the shortwave range from 6 MHz to 22 MHz. Coil L1 serves as the shortwave oscillating coil for the 6SA7 vacuum tube and is commercially available. Capacitor C1 is a variable capacitor with a capacitance range...
WWV receiver circuit
The RF amplifier Q3 connects to diodes D1 to D4 within the mixer. Transistors Q1 and Q2, through transformers T1 and T2, facilitate the injection of liquid oxygen at 10 MHz for diodes D1, operational amplifier U1A, and U1B. Operational...
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...
Antenna Low Power RF & Wireless Connectivity
The "green area" is designated for the placement of the TRF7970A's antenna, which should be connected between two 0-ohm resistors. The antenna can be constructed step by step following the guidelines in the document "Antenna Matching for the TRF7960 RFID...
TV Muter Circuit
Many households still have tube-type television sets. Connecting one of these large televisions to a stereo system to enhance sound quality is generally straightforward, as numerous SCART to Cinch adapters are available in accessory stores. However, some television sets may...
The R2 Single Sideband Direct Conversion Receiver
The old common-base audio preamp, which has a noise figure of 5 dB, is a clear candidate for improvement in noise performance. A common-emitter configuration with shunt feedback provides an input resistance of 50 ohms, which is preferred by the...
wave antenna circuit
The circuit illustrated here demonstrates that, despite advancements in components and technology, it remains possible to design effective and intriguing circuits. This design utilizes two well-known transistors, the BF256C and the BF494. Along with the necessary resistors and capacitors, these...
15w rf amplifier circuit
An RF power amplifier is a type of electronic amplifier used to convert a low-power radio-frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter. It is optimized for high efficiency, high output...
RF isolation amplifier
This wideband RF isolation amplifier has a frequency response of 0.5 to 400 MHz ± 0.5 dB. This two-stage amplifier can be utilized in applications that require high reverse isolation, such as receiver intermediate-frequency (IF) strips and frequency distribution systems....
