The SGA-6489 amplifier is a radio frequency (RF) amplifier, designed to increase the power of telecommunications signals in broadcast, network, and other electronic communication systems. It is designed to support multi-band applications, and is a high-efficiency, low-noise amplifier (LNA) with fast settling times. The SGA-6489 features both an amplifier and a power detector, which together provide accurate dynamic range measurements and control of output power.

The amplifier includes a general power amplifier design and a high-efficiency switching mode (SMPS) power amplifier. The amplifier features high small-signal gain and low noise figure for use in applications requiring low noise or high linearity. It also features linear operation when operated with higher gain. The SGA-6489 also offers high power-added efficiency (PAE) when operating in higher linearity applications.

The SGA-6489 offers up to 45 dB of gain and up to +47 dBm of output power. It can be operated over temperatures ranging from -40°C to +85°C. The amplifier has a low power consumption and is RoHS compliant. The amplifier also has TTL programmable control and a lockout mode, allowing for simplified control of power levels ranging from 0 dB to full output.

The SGA-6489 power detector has a high overload capability to allow system monitoring of signals in the presence of strong signals or interference. It offers both peak and average power detection, with an accuracy of ± 1 dB or better up to +20 dBm. The power detector can be operated over temperatures ranging from -40°C to +85°C.

In summary, the SGA-6489 is a high-efficiency, low noise RF amplifier with a power detector, which together provide accurate dynamic range measurements and control of output power. The amplifier has the ability to provide up to +47 dBm of output power, with a high power-added efficiency, and the power detector allows system monitoring of signals in the presence of strong signals or interference. The overall design of the SGA-6489 makes it an ideal solution for multi-band applications, and its low power consumption makes it an attractive choice for a range of RF systems.
