Evaluating the ADRF6820—a 695 MHz to 2700 MHz Quadrature Demodulator with
Integrated Fractional-N PLL and VCO
FEATURES
GENERAL DESCRIPTION
Full featured evaluation board for the ADRF6820
On-board USB for SPI control
Dual supply: 5 V and 3.3 V operation
C# software interface for serial port control
The ADRF6820 is a highly integrated quadrature demodulator and
synthesizer ideally suited for next generation communication
systems. The feature rich device consists of a high linearity,
broadband quadrature demodulator; an integrated fractional-N
phase-locked loop (PLL); and a low phase noise multicore voltage
controlled oscillator (VCO). In addition, the ADRF6820 integrates
a 2:1 RF switch, an on-chip tunable RF balun, a programmable
RF attenuator, and two low dropout (LDO) regulators. This
highly integrated device fits within a small 40-pin, 6 mm ×
6 mm footprint.

EVALUATION BOARD HARDWARE
RF INPUTS
The ADRF6820 evaluation board provides all of the support
circuitry required to operate the ADRF6820 in its various
modes and configurations. Figure 2 shows the typical bench
setup used to evaluate the performance of the ADRF6820.
POWER SUPPLY
The ADRF6820 evaluation board requires a quiet 6 V power
source. This 6 V power source feeds the power supply design on
the ADRF6820 evaluation board that consists of switches and
dc regulators. Via the switches and/or dc regulators, 3.3 V and
5.0 V power rails are provided to the main IC.
The high isolation 2:1 RF switch and on-chip tunable RF balun
enable the ADRF6820 to support two single-ended, 50 Ω terminated RF inputs. The 2:1 RF switch can be controlled serially via
the SPI port or in parallel via Switch S1. The default configuration
is parallel control using the switch. The operational frequency
range of the RF inputs is from 695 MHz to 2700 MHz; these
inputs should be ac-coupled.

The ADRF6820 offers two alternatives for generating the
differential local oscillator (LO) input signal:
•
•
Generate the signal externally via a high frequency, low
phase noise LO signal.
Generate the signal internally via the on-chip Fractional-N
synthesizer.
transformer/balun roll-off. However, to terminate the ADRF6820
with 200 Ω and also match the output impedance of the
transformer with 50 Ω, an L network is placed between the
I/Q outputs and the transformer. This introduces some power
loss because the L network acts as a voltage divider (see Figure 3).
The power loss due to the L network is approximately 17 dB.

In either case, the differential LO signal can be routed off chip
to SMA connectors labeled LOOP and LOON for the purpose
of daisy-chaining multiple ICs requiring LO signals.
For an internal LO configuration using the on-chip Fractional-N
synthesizer, apply a low phase noise reference signal to the
REF_IN connector. The PLL reference input can support a wide
frequency range because the divide or multiplication block can
be used to increase or decrease the reference frequency to the
desired value before the signal is passed to the phase frequency
detector (PFD). The integrated synthesizer enables continuous
LO coverage from 356.25 MHz to 2850 MHz.
For optimum performance using an external LO source, the LO
input pins (LOIN− and LOIN+) should be driven differentially. The
wide input range of the external LO inputs span from 350 MHz
to 6000 MHz. Unless an ac-coupled balun/transformer is used
to generate the differential LO, the inputs must be ac-coupled.
The input impedance of the differential LO signals is 50 Ω.
QUADRATURE I/Q OUTPUTS
On the evaluation board, the quadrature I/Q outputs are terminated with 200 Ω differential. This is achieved by using a
1:1 transformer and an L-impedance matching network. The
1:1 transformer, TC1-1-13M+ from Mini-Circuits, is a very
wide bandwidth (4.5 MHz to 3000 MHz) transformer that allows a
flat pass-band response of up to 1 GHz. Using a wide bandwidth
transformer is necessary to accurately evaluate the wideband
pass-band response of the ADRF6820 without the effects of the

Figure 3. I/Q Output Matching Network
To avoid the power loss from the L network while achieving the
proper impedance matching, a 4:1 impedance transformer, such
as the TC4-1W+ from Mini-Circuits can be used in place of the
TC1-1-13M+. This 4:1 impedance transformer allows the primary
side of the transformer to be terminated with 200 Ω and the
secondary side to be terminated with 50 Ω. The L network then
becomes unnecessary and can be shorted out by replacing R35,
R36, R37, and R38 with 0 Ω while R31, R32, R33, R34, R39, R40,
R41, and R42 can all be DNI (do not install). Attention needs to
be paid to the bandwidth of the transformer because impedance
transformation transformers tend to have narrower bandwidths.
The TC4-1W+ has a listed bandwidth of 3 MHz to 800 MHz;
however, the 1 dB bandwidth is limited to 100 MHz. As a result,
the roll-off of the transformer may distort the pass-band flatness of
the ADRF6820, depending on which bandwidth configuration
is used for the ADRF6820.

EVALUATION BOARD CONTROL SOFTWARE
The ADRF6820 evaluation board is configured with a USB friendly
interface to allow programmability of the ADRF6820 registers.
SOFTWARE INSTALLATION PROCEDURES
The following instructions describe how to install the ADRF6820
control software, as well as the Cypress generic USB driver, on a

Before reading or writing to the registers, validate the USB
connection by reading the USB indicators located in the
lower left corner of the main window.
Click Update GUI to read the register values from the
device and update the user interface. (An automatic write
to the chip is initiated every time a register value is
changed from the user interface.)
Specify the PLL reference and the desired LO frequency by
typing the appropriate values into the designated boxes.
Press ENTER after each input, and the software (via the
PLL synthesizer blocks) calculates and sets the INT, FRAC,
and MOD values accordingly.
