circuit
The MMIC is very suitable as IF amplifier in e.g. LNB’s.
The excellent wideband characteristics make it an easy
building block.

internally matched to 50 Ω, and therefore does not need any external matching. The value
of the input and output DC blocking capacitors C2 and C3 should not be more than 100 pF
for applications above 100 MHz. However, when the device is operated below 100 MHz,
the capacitor value should be increased.
The 22 nF supply decoupling capacitor C1 should be located as close as possible to the
MMIC.
The PCB top ground plane, connected to pins 2, 4 and 5 must be as close as possible to
the MMIC, preferably also below the MMIC. When using via holes, use multiple via holes
as close as possible to the MMIC.
