1. The data rate may be increased by increasing the PLL Loop Bandwidth, see Page10 or use ADIsimPLL.
2. Optimized for FSK. For ASK or OOK typically need to increase the Loop BW to greater than 100kHz to avoid VCO pulling
3. Simple mother board for direct register programming and radio performance evaluation.
4. Controller mother board to run ADIismLINK protocol for range testing, PER measurements , system development etc.

GENERAL DESCRIPTION
The ADF7020 and ADF7020-1 are FSK/GFSK/ASK/OOK
transceivers which are designed for operation in the licensed
and unlicensed VHF/UHF bands from 80MHz to 956MHz.
There are different versions of the evaluation board available
which are optimized for particular frequency bands. The
daughter-board contains all the required components for
operation of the radio, including loop filter, output matching,
antenna and connector to mother board.
To control the ADF7020/ADF7020-1 register settings via the PC
you will need the EVAL-ADF70XXMB mother board. This
technical note describes usage with the EVAL-ADF70XXMB
boards. This is the recommended board for detailed evaluation
and RF testing of the parts.
The EVAL-ADF70XXMB2 controller board comes as part of
the ADF702X Development Kit. This mother board allows the
user to set up a network of units using the ADIismLINK
protocol and thus evaluate the parts performance in a
networked environment. Further details and documentation on
the EVAL-ADF70XXMB2 development platform is available on
the

EVAL-ADF7020-XDBX HARDWARE DESCRIPTION The RF module, which is plugged into the mother board, consists of the ADF7020 or ADF7020-1 device, output matching circuit optimized for operation in a certain frequency band, harmonic filter, PLL loop filter, de-coupling and xtal. This RF module provides a low-cost, optimally matched RF reference design which you can use as a starting point for your design ...

... ADF7020/ADF7020-1. Initial Setup As described in the Hardware Description section, the evaluation board is divided into two module containing the ADF7020 and a mother-board which accepts the RF module and contains the power supply block and some I/O pins. You need to mount the RF module onto the mother- board, ensuring correct alignment by having the drill-holes in the module above the screw-holders on the mother board ...

Evaluation board setup for Rx mode Use a supply of 3V and the setup as shown in Figure 13 important to note that the ADF7020/ADF7020-1 uses a low-IF architecture where the IF is operating at 200kHz. This means the LO frequency should be set to 200kHz below the incoming RF frequency ...

... EVAL-ADF7020-XDBX 13. If you don’t have a built-in BER tester you can estimate the sensitivity point, by reducing the level on the frequency generator until you see the RxTxData waveform ‘flickering’ which corresponds to errors in the recevied data. Typically if you see a flicker/error once per second you can roughly estimate this to be the sensitivity point ...

... OR ADF7020-1DBX The EVAL-ADF70XXMB2 boards which contain an embedded microcontroller running a wireless network protocol is the simplest way to setup and RF Link. If you are using the EVAL- ADF70XXMB boards it is still possible to setup a basic link using the antennas and software provided. The most straight- forward way to do this is to have one board acting as a dedicated Transmitter and one board as the dedicated Receiver ...
