SW1
Supply and Ground Vector Pins
Device Enable:
When in position A, the ENBL
pin is connected to +V
S
and the AD8314 is in
operating mode. In Position B, the ENBL pin is
grounded, putting the device in power-down mode.
Input Interface:
The 52.3
resistor in position
R2 combines with the AD8314’s internal input
impedance to give a broadband input impedance
of around 50
. A reactive match can be imple-
mented by replacing R2 with an inductor and
R1 (0
) with a capacitor. Note that the AD8314’s
RF input is internally ac-coupled.
Output Interface:
R4, C2, R6, and C3 can be
used to check the response of V_UP and V_DN
to capacitive and resistive loading. R3/R4 and
R5/R6 can be used to reduce the slope of V_UP
and V_DN.
Power Supply Decoupling:
The nominal supply
decoupling consists of a 0.1
μ
F capacitor (C1). A
series inductor or small resistor can be placed in
R9 for additional decoupling.
Filter Capacitor:
The response time of V_UP
and V_DN can be modified by placing a capacitor
between FLTR (pin 4) and V_UP.
Slope Adjust:
By installing resistors in R7 and R8,
the nominal slope of 20 mV/dB can be increased.
See Slope Adjust discussion for more details.
Measurement/Controller Mode:
LK1 shorts
V_UP to VSET, placing the AD8314 in
measurement mode. Removing LK1 places
the AD8314 in controller mode.
