THEORY OF OPERATION

The HMC6505A is a GaAs, pHEMT, MMIC I/Q upconverter

with an integrated LO buffer that upconverts IF between dc to

3 GHz to RF between 5.5 GHz and 8.6 GHz. LO buffer

amplifiers are included on chip to allow LO drive range of up

to 6 dBm for full performance. The LO path feeds a quadrature

splitter followed by on-chip baluns that drive the I and Q singly

balanced cores of the passive mixers. The RF output of the I and

Q mixers are then summed through an on-chip Wilkinson power

combiner and relatively matched to provide a single-ended, 50 Ω

output signal that is amplified by the RF amplifiers to produce a

dc-coupled and 50 Ω matched RF output signal at the RFOUT

port. A voltage attenuator precedes the RF amplifiers for desired

gain control.
