Description
Power Supply and Ground Clip Leads.
Device Enable. Apply either 5 V or 0 V to the SMA connector labeled ENBL to enable or disable
the IQ modulator section of the circuit. If the ENBL SMA connector is left open, this node is
pulled high by R22, enabling the IQ modulator.
Modulator VVA Interconnect. The output of the IQ modulator is available at the VMOD SMA
connector. The input and output of the VVA can be accessed through the ATTIN and ATTOUT
SMA connectors. The IQ modulator output can be connected to the VVA by installing a 0 Ω
resistor at R2 and a 1000 pF capacitor at C19. In this mode, C9 and C12 should be removed.
Baseband Input Filters. These component pads can be used to implement a low-pass filter for
the baseband input signals.
