MAX2363ETM+T

MAX2363ETM+T is a two-chip, high-performance, low-power Radio Frequency (RF) transmitter module for use in short-range applications such as global system for mobile communications (GSM) systems. This transmitter includes an on-board power amplifier, T/R switch, low-noise amplifier (LNA), micropower oscillator and mixer all in a small direct-solvent-mount (DSM) module format. The MAX2363ETM+T transmitter supports up to 500 mW of RF output power depending on temperature, voltage and load. This transmitter uses a unique self-calibrating voltage-controlled oscillator (VCO) and circuit design to deliver excellent RF performance and low total harmonic distortion (THD) over the entire operating range--both DC and RF.

The MAX2363ETM+T transmits digital data in the frequency range of 0.9 GHz -2.7 GHz. Data is transmitted by modulating the VCO frequency and amplitude. The on-board RF power amplifier stage provides up to 500mW of RF output power with a typical 0.7dB noise figure. The receiver uses a low-noise amplifier (LNA) to provide gain and impedance matching between the RF signal source and the MAX2363ETM+T. The transmitter includes a power control circuit to adjust the frequency and amplitude of the transmitted signal.

The MAX2363ETM+T includes a T/R switch that can be configured to one of two operating modes; transmit (TX) or receive (RX). When the transmitter is in TX mode, it drives the antenna to transmit the RF signal. In RX mode, the T/R switch is activated to disconnect the VCO from the antenna and connect to the LNA input. This allows the receiver to detect and receive the signal from the antenna.

The MAX2363ETM+T is designed with an embedded on-chip mixing circuit and a PCM digital input. This allows it to process the data and convert it to the appropriate digital format to be used by the transmitter. The microphone interface is designed to combine the analog audio signal with the digital information. This combination eliminates the need for a separate digital-to-analog converter for the audio signal and provides a faster, higher-quality transmission.

In summary, the MAX2363ETM+T is a highly integrated, low-power, small form-factor RF transmitter module for short-range applications. The device incorporates an on-board power amplifier, low-noise amplifier, T/R switch and on-chip mixer into a single package. It supports up to 500 mW of RF output power and a typical 0.7dB noise figure. The MAX2363ETM+T is ideal for short range transmission of data in the frequency range of 0.9GHz -2.7GHz and is suitable for global system for mobile communications (GSM) systems.
