MTX-102
UHF AM Transmitter Module

Description

The MTX-102 is an on-off keyed (OOK) and amplitude shift keyed (ASK) high performance, ultra compact, long range transmitter for remote wireless applications. The transmitter operates at 315, 390, 418, and 433 MHz, and is primarily intended for use in part 15.231 systems. Because all tuning is automatic and the transmitter functions are completely integrated, this module is both a highly reliable and low cost solution for high volume wireless applications. An external antenna is the only component required, therefore the MTX-102 can be easily integrated into other applications, which has the benefit of eliminating design and production costs and improving time to market.

The MTX-102 employs a unique feature which tunes the antenna to the internal UHF synthesizer. The transmitter normally complies with worldwide UHF unlicensed band intentional radiator regulations, and also is compatible with virtually all ASK/OOK receiver types. The MTX-102 is designed to work with transmitter data rates from 100 to 20k bits per second. The automatic tuning coupled with a preset PA level ensures that the transmitter output power remains constant for the life of the battery. When used with the family of MRX receivers, the MTX-102 provides an inexpensive and reliable wireless soluion that is suitable for a wide variety of RF applications, specifically OEM applications.
