In a Radio Frequency (RF) linear amplifier, the RF Choke (RFC) is a specialized inductor designed to act as a “frequency-selective gatekeeper.” Its primary role is to provide
In rural Kerala, geographical hurdles like dense rubber plantations and hilly terrain often weaken 4G signals. Since most Indian providers use the 1800 MHz (Band 3) and 2300
In the world of amateur radio, the choice between a MOSFET and a JFET isn’t about which is “better” overall, but rather which is better for the specific
In amateur radio, Automatic Gain Control (AGC) and Automatic Level Control (ALC) serve the same fundamental purpose—maintaining a steady signal level—but they operate on opposite sides of the
In RF (Radio Frequency) design, while standard single toroids are common, binocular toroids (also called multi-aperture or “pig-nose” cores) are often the preferred choice for broadband transformers and
BN43-7051 is a high-quality ferrite binocular core (also known as a “multi-aperture core”) used in radio frequency (RF) applications. I bought these from VU2PTI (https://www.homebrewradios.com/) Technical Specifications This
15 turns of 20 SWG wire on a 11mm former as per VU2EVQ design. Calculated length of the coil was 0.914*15 = 13.71 mm (1.371cm). Inductance calculated by
