Miniature FM Radio Modules Have No Adjustable Components

The RTFQ1 and RRFQ1 miniature FM radio modules provide high performance radio data links at 433.92 MHz and have no adjustable components. Manufactured using laser-trimmed, thick-film ceramic hybrids, the modules exhibit stable electronic characteristics over a temperature range of -25°C to 80°C. By combining the RTFQ1 transmitter and RRFQ1 receiver, users can implement a single RF link with an in-building range of up to 250' and 800' on open ground. The modules can also achieve data rates of 4.8 Kb/s from any standard CMOS/TTL source. Because of their compact size (20 mm x 11 mm x 4 mm and 38 mm x 18 mm x 4 mm) and low-power requirements (7 mA), the modules suit battery-powered one-to-one and multi-node systems, such as hand-held terminals, EPOS, inventory tracking, and car security. Quantity prices start at $9. OKW ELECTRONICS, Bridgeville, PA. (412) 220-9244.
