Wideband Distributed Amplifier
30 kHz – 50 GHz
MAAM-011275
Rev. V1
Operating Conditions
2 bypass capacitors of 100 pF and 1 µF should be
connected to V
DAUX
. This provides for improved gain
flatness below 2 GHz down to 30 kHz when
required.
The recommended biasing conditions are V
DD
= 7 V
and I
DSQ
= 200 mA, with I
DSQ
set by adjusting V
G1
after correctly setting V
DD
(refer to turn on
sequence). To maintain the best performance
MACOM recommends using an active bias circuit for
constant I
DD
.
The 100 pF capacitor can be a single layer capacitor
or an SMT device on the PCB. Although it should be
positioned as closely to the device as practically
possible, the frequency response is not particularly
sensitive to this. The 1
μ
F capacitor can be placed
further away on the PCB.
It is noted that any biasing arrangement used,
including active biasing, must be able to source at
least 10 mA into the V
G1
port. This is because the
V
G1
port contains a resistive divider with a total
resistance to ground of 244
Ω.
For the
recommended I
DSQ
of 200 mA obtained at a V
G1
voltage of around 2.5 V, 10 mA of V
G1
current (I
G1
) is
expected. These values of V
G1
and I
G1
will vary
slightly between devices.
Data in this datasheet was measured using 100 pF
(C1) and 1 µF (C3) capacitors on V
DAUX
.
For biasing V
DD
, apply V
DD
through a bias tee
connected to the RF
OUT
/V
DD
port and connect an
external DC block to the RF
IN
port. This provides
wide band performance of 40 MHz to 50 GHz
(depending on the bandwidth of the bias tee).
