High Performance ISM Band

ASK/FSK Transmitter IC

Preliminary Technical Data

ADF7901

is capable of Frequency Shift Keying (FSK) modulation on

8 different channels, selectable by 3 external control lines. OOK

modulation is performed by modulating the PA control line.

FEATURES

Single chip low power UHF transmitter

369.5 MHz to 395.9 MHz frequency operation using

Fractional-N

PLL and fully integrated VCO

The on-chip VCO operates at 2 × the output frequency. The

divide by 2 at the output of the VCO reduces the amount of PA

feedthrough. As a result of this, OOK modulation depths of

greater than 50 dB are easily achievable.

3.0 V supply voltage

Data rates supported < 2.5 kbps

Low current consumption 26 mA at 12 dBm

Output at 384 MHz

Power-down mode (< 1 µA)

24-Lead TSSOP package

The FSK_ADJ and ASK_ADJ resistors can be adjusted in the

system to optimize output power, for each modulation scheme.

An additional 1.5 dB of output power is provided for the lower

bank of channels to adjust for antenna performance. The CE

line allows the transmitter to be powered down completely. In

this mode, the leakage current is typically 0.1 µA.

GENERAL DESCRIPTION

The ADF7901 is a low power OOK/FSK UHF transmitter

designed for use in RF Remote Control Devices. The device
