RF amplifiers enable signal transmission over great distances by amplifying the signal while retaining its information-bearing components. The MD7IC2755GNR1 is an RF amplifier specifically designed to amplify Medium Wave and Shortwave signals. This RF amplifier offers superior signal strength and high performance with excellent stability and reliability.

Application Field

The MD7IC2755GNR1 is widely used in cellular communication systems, such as GSM, WCDMA, LTE, 5G, and other data rate wireless systems. It is also suitable for WiFi, Bluetooth, Zigbee, and other short-range wireless communication standards. Additionally, it is well-suited for applications such as radio frequency identification (RFID), navigation, automated meter reading, medical ultrasound, and other areas where signal transmission requires wide transmitting power and long range.

Working Principle

The MD7IC2755GNR1 is a single-stage RF amplifier that runs on a 2.7 to 5.5 volts supply voltage. The two-stage matching network of the device uses two capacitors and an inductor that isolates the source from the RF output. This matching network provides optimal impedance matching for best performance. It then uses a three-level power amplifier configuration which provides 50dB small signal gain, 27dBm of output power and -75dBc of second-order distortion at 2.1V operating voltage. Moreover, the output voltage swing can reach up to 6 volts.

The MD7IC2755GNR1 also features both enabling and input gain control, allowing easy control of the frequency response and gain. The enabling feature allows the user to switch between low noise and low distortion operation. The input gain control can also be adjusted to accommodate different signal levels. The device also has integrated temperature protection, allowing safe operation even in harsh environments.

In summary, the MD7IC2755GNR1 is an excellent RF amplifier designed for a wide range of application fields. With its superior signal strength and high performance, it is sure to satisfy the most demanding requirements. It is an ideal choice for modern cellular, short-range, medical ultrasound, and navigation applications.
