RF Input Interface
The IN+ and IN- pins are differential RF inputs, which can be externally configured as differential or single-ended
input. Power match components are placed at these input terminals, along with DC blocking capacitors. The
coupling capacitor values also set the lower spectral boundary of the input signal bandwidth. The inputs can be
reactively matched (refer to input return loss graphs), but a resistor network should be sufficient for good wideband
performance.
Selecting resistor values for Differential Interface:
The value of R25 depends on the balun used; if the balun is
50Ω on both sides of the SE-Diff conversion,
then R25
, Ω , where
RM = the
desired power match impedance in
ohms
For RM = 50 Ω, R25 = 64.7 Ω ≈ 68 Ω
Single-Ended Input Interface
Tuned SE-interface: for signal frequencies > 900MHz
Choose L and C elements from the following graph for
narrowband tuning of the SE-interface: R5 = 27Ω, R1 = 82Ω,
C2 = 100 pF, R2 = 0Ω, L1, C3 - see graph.
Wideband SE-interface: for signal frequencies < 900MHz
R5 = 27Ω, R1 = 82Ω,
C2, C3 are 1nF decoupling caps.
R2 is 0Ω, and R25 is open
For wideband (un-tuned) input interfaces, choose the input decoupling capacitor values by first determining the lowest
spectral component the power detector is required to sense, L.
Input decoupling capacitor value
, Farads, where L is in Hertz.
Ex. If the power detector needs to sense down to 10MHz, the decoupling capacitor value should be
1/(π*10E6*3.2) = 10nF
A DC bias (Vcc-0.7V) is present on the IN+ and IN- pins, and should not be overridden.
