The MTX-103 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 the 902-928 MHz band, and is primarily intended for use in part 15.247 and 15.249 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-103 can be easily integrated into other applications, which has the benefit of eliminating design and production costs and improving time to market.
The MTX-103 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-103 is designed to work with transmitter data rates up to 115k bits per second. The automatic tuning coupled with a preset PA level ensures that the transmitter output power remains constant at maximum regulatory transmit power limits for the life of the battery. When used with the family of MRX receivers, the MTX-103 provides an inexpensive and reliable wireless solution that is suitable for a wide variety of RF applications, specifically OEM applications.
