High Performance ISM Band

OOK/FSK Transmitter IC

ADF7901

FEATURES

GENERAL DESCRIPTION

Single-chip, low power UHF transmitter

369.5 MHz to 395.9 MHz frequency operation using

fractional-N PLL and fully integrated VCO

The ADF7901 is a low power OOK/FSK UHF transmitter

designed for use in RF remote control devices. It is capable of

frequency shift keying (FSK) modulation on eight different

channels, selectable by three external control lines. OOK

modulation is performed by modulating the PA control line.

3.0 V supply voltage

Data rates up to 50 kbps supported

Low current consumption

26 mA at 12 dBm output at 384 MHz

Power-down mode (<1 μA)

24-lead TSSOP

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

division by 2 at the output of the VCO reduces the amount of

PA feedthrough. As a result, OOK modulation depths of greater

than 50 dB are easily achievable.

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.
