RFFC2071 Datasheet, PDF (10/23 Pages) RF Micro Devices – 2.7GHz RF SYNTHESIZER/VCO WITH INTEGRATED RF MIXER

RFFC2071/2072
ULATION bits, the VCO frequency is instantly updated. An arbitrary frequency modulation can then be performed dependant
only on the rate at which values are written into the FMOD register.
The modulation frequency is calculated according to the following formula:
F_MOD = 2^MODSTEP  F_PD  MODULATION  2¹⁶
Where MODULATION is a 2's complement number and F_PD is the phase detector frequency.
Programming Information
The RFFC2071 and RFFC2072 share a common serial interface and control block. Please refer to the register map and pro-
gramming guides which are available for download from http://rfmd.com/products/IntSynthMixer/.
Evaluation Boards
Evaluation boards for RFFC2071 and RFFC2072 are provided as part of a design kit, along with the necessary cables and pro-
gramming software tool to enable full evaluation of the device. The evaluation board has been configured for wideband opera-
tion. The mixer inputs and outputs are connected to wideband transmission line transformer baluns. Design kits can be
ordered from www.rfmd.com or from local RFMD sales offices and authorized sales channels. For ordering codes please see
“Ordering Information” on page 23. For further details on how to set up the design kits please refer to the user guide which can
be downloaded from http://rfmd.com/products/IntSynthMixer/.
