CONTROL INPUTS

The ADRF5515-EVALZ evaluation board has four control
inputs, described in Table 2. Each control input is decoupled
with a 100 pF capacitor.

BP_A Bypass LNA Stage 2 on Channel A
BP_B Bypass LNA Stage 2 on Channel B
PD Power down all LNA stages on Channel A and
Channel B
SWCTRL Control switches on Channel A and Channel B

RF INPUTS AND OUTPUTS

The ADRF5515-EVALZ evaluation board has ten edge
mounted Subminiature Version A (SMA) connectors for the
RF inputs and outputs, as shown in Table 3. The
covers the 3.3 GHz to 4.0 GHz frequency range and does not
require any external matching components.
By default, the evaluation board comes assembled and shipped
without SMA connectors and series components on the thru
lines. To measure and calibrate out the board loss effects, the
user must connect these connectors and components. Use the
thru line on THRU1 and THRU2 to calibrate out the ANT_A/
ANT_B to TERM_A/TERM_B board loss. Use the thru line on
THRU3 and THRU4 to calibrate out the RXO_A/RXO_B board
loss.
