Baseband Amplifier Output Bias: Installing this link connects VREF
to VCMO. This sets the bias level on the baseband amplifiers to VREF,
which is equal to approximately 1 V. Alternatively, the bias level of the
baseband amplifiers can be set by applying an external voltage to SMA
connector J11.
AGC Mode: Installing LK2 and LK6 connects the mixer outputs IMXO
and QMXO to the detector inputs VDT2 and VDT1. By installing LK3,
which connects VGIN to VAGC, the AGC mode is activated. The AGC
voltage can be observed on SMA connector J9. With LK3 removed, the
gain control signal for the internal variable gain amplifiers should be
applied to SMA connector J10.
Baseband Filtering: Installing LK4 and LK5, connects the mixer
outputs IMXO and QMXO directly to the baseband amplifier inputs
IAIN and QAIN. With R6 and R33 installed (0
), IAIN and QAIN
can be observed on SMA connectors J7 and J8. By removing LK4 and LK5
and installing R8 and R34, LC filters can be inserted between the
mixer outputs and the baseband amplifier inputs. R8 and R34 can be
used to increase the effective output impedance of IMXO and QMXO.
(These outputs have low output impedances.) R39 and R40 can be used
to provide terminations for the filter at IAIN and QAIN. (IAIN and QAIN
are high impedance inputs.) R39 and R40 are terminated to VREF.

Device Enable: When in position A, the ENBL pin is connected to +V
S
and the AD8347 is in operating mode. In position B, the ENBL pin is
grounded, putting the device in power-down mode.
