FUNCTION
0 = LNA low-gain state.
1 = LNA high-gain state.
GAINSET
Gain set

1
For manual gain control, enable the AGC (AGC_EN =
1), set LNA gain state to desired setting, then disable
the AGC (AGC_EN = 0).
FSKCALLSB = 1 enables a longer, more accurate

FSK calibration.
FSKCALLSB = 0 provides for a quick, less accurate
FSK calibration.
This bit enables the FDATA pin to act as the serial

Layout Considerations
A properly designed PCB is an essential part of any
RF/microwave circuit. On high-frequency inputs and
outputs, use controlled-impedance lines and keep
them as short as possible to minimize losses and radia-
tion. At high frequencies, trace lengths that are on the
order of λ /10 or longer act as antennas.
Keeping the traces short also reduces parasitic induc-
tance. Generally, 1in of a PCB trace adds about 20nH
of parasitic inductance. The parasitic inductance can
have a dramatic effect on the effective inductance of a
passive component. For example, a 0.5in trace con-
necting a 100nH inductor adds an extra 10nH of induc-
tance or 10%.
To reduce the parasitic inductance, use wider traces
and a solid ground or power lane below the signal
traces. Also, use low-inductance connections to ground
on all GND pins, and place decoupling capacitors
close to all V DD or HVIN connections.
