LW203M
300-900MHz ASK Transmitter Module
Introduction
LW203M is an AM transmitter module using Lexiwave’s LW203 RFIC designed for ASK communication systems. It consists of a Colpitts oscillator together with a RF power amplifier. Targeted applications are in the frequency band from 300MHz to 928MHz. By using an appropriate SAW resonator, LW203M can support both 315/433MHz and 886/915MHz UHF bands for ASK communication at low cost without any tuning. For 915MHz frequency, using variable inductor or micro-strip line as a resonator offers super low-cost solutions for short to medium communication range applications. It is a complementary module to Lexiwave’s LW103M ASK receiver module to form a complete RF solution for ASK communication. A communication range of 150 meter in open area is typical.
