CHV2241
K-band Oscillator with integrated Q-band Harmonic
Mixer
GaAs Monolithic Microwave IC
Description
The CHV2241 is a monolithic multifunction
proposed for frequency generation and
transposition. It integrates a K-band oscillator, a
Q-band harmonic mixer and buffer amplifiers.
For performance optimisation, an external port
(ERC) allows a passive resonator coupling to
the oscillator (at half output frequency). All the
active devices are internally self biased.
The circuit is manufactured with the P-HEMT
process : 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
Main Features

n High temperature range
n On chip self biasing
n Automatic assembly oriented
n Chip size 1.82 x 0.97 x 0.1 mm

(1) The centre frequency is given by the external passive resonator.
See part “Proposed external high Q resonator“ for frequency temperature drift
example.
DRO frequency long term stability is DR environment stability dependant
(hermeticity …).
(2) This characteristic depends on the external resonator Q, the given performance has
been obtained by using an external dielectric resonator (see section “Proposed External
High Q resonator”)
(3) Without external filtering
(4) Negative supply voltage must be applied at least 1us before positive supply
voltage.
