Press Release Summary:
ASK (Amplitude Shift Keyed) pair, Model MICRF005 receiver and Model MICRF103 transmitter, provide up to 115 kbps data rate at operating frequencies from 800 MHz to 1 GHz for short-range wireless applications. MICRF005 requires only 2 capacitors and a reference oscillator to implement complete RF receiver. Both devices operate from 5 V supply. MICRF005 consumes 10 mA supply current, while MICRF103 consumes 16 mA.

QwikRadio(TM) Transmitter-Receiver Pair Handle 115kbps Data-Rate at 800MHz-1GHz
o highly integrated
o ideal for cost sensitive applications
SAN JOSE, Calif. -- (October 3, 2002) - Aimed at low-cost short-range wireless applications, an ASK (Amplitude Shift Keyed) transmitter-receiver pair providing up to 115kbps data-rate at 800MHz-1GHz operating frequency is now available from Micrel Semiconductor (NASDAQ: MCRL), an industry leader in analog and broadband communications integrated circuits.
The MICRF005 receiver and MICRF103 transmitter are the latest additions to Micrel's family of QwikRadio(TM) RF products. The transmitter-receiver pair provides a unique combination of data-rate, low cost, low power and ease of use. The devices are more highly integrated and easier to use than earlier RF ICs. Only hybrid modules provide similar levels of integration; but at a much higher cost.
"Micrel's earlier MICRF003 receiver supports up to 20kbps in the same 800MHz-1GHz frequency band. Many designers came to us asking for the same low cost and ease of use but at higher data-rates," said Scott Brown, Linear and RF Business Unit Manager. "The MICRF005 is our response to those requests."
The MICRF005, like all other QwikRadio receivers, requires just three external components -- two capacitors and a reference oscillator -- to implement a complete RF receiver. One of the capacitors sets the attack/decay time of the on-board the AGC (automatic gain control); the second capacitor sets the data demodulator slicing threshold; and the reference oscillator determines the receive frequency.
Target applications include wireless keyboards, video game controllers, home security, HVAC systems, and home automation.
Both devices operate off a 5V supply. The MICRF005 consumes 10mA supply current; the MICRF103 consumes 16mA.
