A limiter PIN diode with a three-layer design can protect a receiver from large input signals while allowing the receiver to function normally when large signals aren’t present. A diode can also be used as an input-power-controlled RF variable resistance to produce attenuation that is a function of the diode characteristics as well as the incident signal amplitude. This application note describes the use of PIN limiter diodes in receiver protectors in detail, as well as their many design characteristics and benefits.
While today’s carrier networks are better than previous generations, providers have a lot of ground to cover to reach the goals promised with 5G technology. In addition to being “greener” for the environment, 5G has goals of 1 ms latency, 100 x network energy efficiency, 20 Gbps peak data rates, and 10 Mps/m2 area traffic capabilities. So, how do we achieve the RF chain 5G objectives and meet ‘green’ network goals? This article discusses how RF Gallium Nitride (GaN) technology can be used for emerging 5G technologies.
After building the world's first all-digital radio transmitter, Cambridge Consultants announced that it now has added a digital receiver to complete its digital radio.
Amplifiers used in wireless infrastructure receiver applications have the key requirements of low noise, high linearity, and unconditional stability. In order to meet these needs, Skyworks has developed a new family of low noise amplifiers (LNAs) implemented in 0.5 µm enhancement mode (E-Mode) pHEMT. The SKY67101-396LF, covering 0.4-1.2 GHz, and the SKY67100-396LF, covering 1.2-3.0 GHz, are appropriate for application in GSM, WCDMA, TDSCDMA, and LTE infrastructure receiver chains. For low cost and efficient use of PCB space, the LNAs are housed in a 2 x 2 mm QFN package and share a common layout among the frequency bands.
Engineers at NASA's Jet Propulsion Laboratory (JPL) have developed a new folding, umbrella-like antenna design that can be deployed from a canister on a CubeSat – a low-cost mini-satellite slightly larger than a cereal box.
