| FM Narrow Band VHF Transmitter Module WP-MKT4 Features * MINIATURE SIL / DIL PACKAGE * NARROW BAND 25 KHz CHANNELS * DATA RATES TO 4800 BITS/S * ANY VHF FREQUENCY SUPPLIED * CRYSTAL STABILISED * 5 VOLT SUPPLY VOLTAGE * INDUSTRY PIN COMPATABLE * AF AND DIFGITAL INPUTS Applications * VEHICLE ALARM SYSTEMS * AUTOMATIC METER READING * FIRE ALARM SYSTEMS * DOMESTIC AND COMMERCIAL SECURITY Compatible Receiver Modules * General Description The WP-MKT4-XXX miniature transmitter VHF radio module enables the implementation of a simple telemetry link at data rates of up to 4800 bit/s when used with one of the compatible MK receiver modules. Available for operation at any VHF frequency these modules are able to transmit to distances of several Km depending on types of antenna used. The WP-MKT4-XXX module will suit one-to-one and multi-node wireless links in applications including building and car security, remote industrial process monitoring and computer networking. Because of its small size and low power requirements, this module is ideal for use in portable battery powered wireless applications.

This pin should ideally be connected to the nearest ground plane (e.g. coax braid, main PCB ground plane etc.) RF OUT (pin2) 50 RF antenna output. To achieve best results the antenna impedance must match that of the module. Data IN (pin 3) This has an impedance of 47K and should be ideally driven by a CMOS logic drive or compatible. GND (pin 4) Supply and data ground connec., connected to pin 1. Vcc (pin 5) Supply should be able to source 15mA at 5 volts.
