Multichannel ISM Band

FSK/GFSK/OOK/GOOK/ASK Transmitter

ADF7012

FEATURES

GENERAL DESCRIPTION

Single-chip, low power UHF transmitter

75 MHz to 1 GHz frequency operation

Multichannel operation using Frac-N PLL

2.3 V to 3.6 V operation

On-board regulator—stable performance

Programmable output power:

−16 dBm to +14 dBm, 0.4 dB steps

Data rates: dc to 179.2 kbps

The ADF7012 is a low power FSK/GFSK/OOK/GOOK/ASK

UHF transmitter designed for short range devices (SRDs). The

output power, output channels, deviation frequency, and mod-

ulation type are programmable by using four, 32-bit registers.

The fractional-N PLL and VCO with external inductor enable

the user to select any frequency in the 75 MHz to 1 GHz band.

The fast lock times of the fractional-N PLL make the ADF7012

suitable in fast frequency hopping systems. The fine frequency

deviations available and PLL phase noise performance facilitates

narrow-band operation.

Low current consumption:

868 MHz, 10 dBm, 21 mA

433 MHz, 10 dBm, 17 mA

315 MHz, 0 dBm, 10 mA

There are five selectable modulation schemes: binary frequency

shift keying (FSK), Gaussian frequency shift keying (GFSK),

binary on-off keying (OOK), Gaussian on-off keying (GOOK),

and amplitude shift keying (ASK). In the compensation register,

the output can be moved in <1 ppm steps so that indirect com-

pensation for frequency error in the crystal reference can be

made.

Programmable low battery voltage indicator

24-lead TSSOP

APPLICATIONS

Low cost wireless data transfer

Security systems

RF remote controls

Wireless metering

A simple 3-wire interface controls the registers. In power-down,

the part has a typical quiescent current of <0.1 μA.

Secure keyless entry
