Functional Diagram
General Description
The HMC258 chip is a compact sub-harmonically
pumped (x2) single ended MMIC mixer with an
integrated LO ampli鏗乪r which can be used as an
upconverter or downconverter. The chip utilizes a
GaAs MESFET technology that results in a small
overall chip area of 0.9mm
2
. The 2LO to RF isola-
tion is excellent eliminating the need for additional
鏗乴tering. The LO ampli鏗乪r is a single bias (+5V)
two stage design with only 0dBm drive require-
ment. A less stringent oscillator design is made
possible by the low LO drive and sub-harmonic
nature of the chip. All data is with the chip in a 50
ohm test 鏗亁ture connected via 0.025mm (1 mil)
diameter wire bonds of minimal length <0.31 mm
(<12 mils).
