UCAMF101RARemote Control for Toba Magic Fountain (434MHz Tx)

MICRF102 Micrel MICRF102 6 December 2006 Functional Description The block diagram illustrates the basic structure of the MICRF102. Identifi ed in the fi gure are the principal functional blocks of the IC, namely the (1, 2, 3, 4, 5) UHF Synthesizer, (6a/b) Buffer, (7) Antenna tuner, (8) Power amplifi er, (9) TX bias control, (10) Reference bias and, (11) Process tuner. The UHF synthesizer generates the carrier frequency with quadrature outputs. The in-phase signal (I) is used to drive the PA and the quadrature signal (Q) is used to compare the antenna signal phase for antenna tuning purposes. The Antenna tuner block senses the phase of the transmit signal at the antenna port and controls the varactor capacitor to tune the antenna. The Power control unit senses the antenna signal and con- trols the PA bias current to regulate the antenna signal to the transmit power.

A PCB antenna loop coupled with a resonator and a resistor divider network are all the components required to construct a complete UHF transmitter for remote actuation applications such as automotive keyless entry. Included within the IC is a differential varactor that serves as the tuning element to insure that the transmit frequency and antenna are aligned with the receiver over all supply and temperature variations.

December 2006 1 MICRF102 MICRF102 Micrel MICRF102 QwikRadio™ UHF ASK Transmitter General Description The MICRF102 is a single chip Transmitter IC for remote wireless applications. The device employs Micrel’s latest Qwi- kRadio™ technology. This device is a true “data-in, antenna- out” monolithic device. All antenna tuning is accomplished automatically within the IC which eliminates manual tuning, and reduces production costs. The result is a highly reliable yet extremely low cost solution for high volume wireless applications. Because the MICRF102 is a true single-chip radio transmitter, it is easy to apply, minimizing design and production costs, and improving time to market. The MICRF102 uses a novel architecture where the external loop antenna is tuned to the internal output stage. This trans- mitter is designed to comply with worldwide UHF unlicensed band intentional radiator regulations. The IC is compatible with virtually all ASK/OOK (Amplitude Shift Keying/On-Off Keyed) UHF receiver types from wide-band super-regenerative radios to narrow-band, high performance super-heterodyne receiv- ers. The transmitter is designed to work with transmitter data rates from 100 to 20k bits per second. The automatic tuning, in conjunction with the external resistor, ensures that the transmitter output power stays constant for the life of the battery. When used with Micrel’s family of QwikRadio™ receivers, the MICRF102 provides the lowest cost and most reliable remote actuator and RF link system available.

The voltage at this pin should be set between 0.15V to 0.35V for normal operation. 2 VDD Positive power supply input for the IC. This pin requires a large capacitor for ripple decoupling. A 4.7μF is recommended. 3 VSS This pin is the ground return for the IC. A power supply bypass capacitor connected from V DD to V SS should have the shortest possible path. 4 REFOSC This is the timing reference frequency which is the transmit frequency di- vided by 32. Connect a crystal (mode dependent) between this pin and V SS , or drive the input with an AC-coupled 0.5V PP input clock. See “Reference Oscillator” section in this data sheet. The crystal needs to have a 10pF load capacitance. 5 STBY Input for transmitter stand by control pin is pulled to V DD for transmit opera- tion and V SS for stand-by mode. The device requires 0.0 volts to be placed in stand by. 6 ANTN Negative RF power output to drive the low side of the transmit loop antenna. The RF output stage is tuned in the data transitions in the ASK pin. 7 ANTP Positive RF power output to drive the high side of the transmit loop antenna. The RF output stage is tuned in the data transitions in the ASK pin. 8 ASK Amplitude Shift Key modulation data input pin. For CW operation, connect this pin to V DD . Several transitions of highs and lows are required to tune the output RF stages.
