Functional Diagram

General Description

The HMC258 chip is a compact sub-harmonically

pumped (x2) single ended MMIC mixer with an

integrated LO ampliﬁer 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 0.9mm². The 2LO to RF isolation

is excellent eliminating the need for additional ﬁl-

tering. The LO ampliﬁer is a single bias (+5V) two

stage design with only 0 dBm drive requirement. 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 ﬁxture connected

via 0.025 mm (1 mil) diameter wire bonds of minimal

length <0.31 mm (<12 mils).
