The HMC483MS8GE is a RF Miscellaneous Integrated Circuit (MISC IC) and Module, designed for operations at 8 GHz to 18 GHz. It consists of an amplifier and a limiter, both in a single package.

The application field of the HMC483MS8GE is getting increasingly wider, from Telecommunications and Industrial to Medical and Aerospace applications. These ICs are widely used in satellite communications, radio transmitters and receivers, microwave links, Wi-Fi systems and radar systems.

The HMC483MS8GE can be used as an Amplifier (PA), Limiter, or Gain Block. It has an integrated output detector and a high linearity, high IP3, high gain distributed amplifier design.

The amplifier is a high dynamic range, single stage distributed amplifier with a single ended MMIC design. It works from Vcc = +2.7V to +3.3V, and draws a maximum current of 10mA when operated at 8GHz. The device has an output power of 30dBm. It is packaged in an ultra-compact SMT package, and has good efficiency and linearity.

The limiter section is a single stage limiter and its operation is based on the Gain Controlling Theory (GCT), which enables it to maintain a constant gain irrespective of the input signal level. It has a maximum output power of 30dBm, with a 1dB compression of 19dBm at an input power of +15dBm. The limiter has a low distortion rating of 0.2%, and a wide dynamic range of 8GHz to 18GHz.

The HMC483MS8GE can be used in various types of applications, including frequency division multiplexing (FDM), frequency hopping (FH) and direct frequency hopping (DFH) systems. It is a high performance IC for a wide range of RF applications, including military and commercial communications, wireless networks, satellite communications, wireless microphones, cellular base stations, and consumer electronics.

The working principle of the HMC483MS8GE is based on the Gain Controlling Theory (GCT). This theory enables the module to automatically adjust the gain of the amplifier and limiter according to the signal level. The GCT enables the IC to accurately detect the signal level, reduce the gain of the amplifier in the output detector circuit, and maintain a constant output power irrespective of the input signal level.

The HMC483MS8GE is a versatile IC, ideal for any application requiring a stable, high performance, and low distortion RF amplifier and limiter. Its small size, low cost, and high performance make it an attractive solution for many RF applications.
