TX5003 Datasheet, PDF (1/6 Pages) RF Monolithics, Inc – 303.825 MHz Hybrid Transmitter

®
· Designed for Short-Range Wireless Data Communications
· Supports RF Data Transmission Rates Up to 115.2 kbps
· 3 V, Low Current Operation plus Sleep Mode
· Stable, Easy to Use, Low External Parts Count
The TX5003 hybrid transmitter is ideal for short-range wireless data applications
where robust operation, small size, low power consumption and low cost are required.
All critical RF functions are contained in the hybrid, simplifying and speeding design-
in. The TX5003 includes provisions for both on-off keyed (OOK) and amplitude-shift
keyed (ASK) modulation. The TX5003 employs SAW filtering to suppress output har-
monics, facilitating compliance with FCC Part 15 and similar regulations.
