The MAAD-011021 is a wide band 6-bit digital
attenuator covering DC to 40 GHz. The attenuation
bit-values are 0.5 dB LSB (least significant bit), 1, 2,
4, 8, and 16 dB for a total attenuation of 31.5 dB.
Attenuation error is typically less than +/- 0.5 dB,
RMS phase error is less than 5 degrees at 20 GHz,
and typical insertion loss is 7.1 dB at 15 GHz.
Return loss is typically 12 dB across all frequencies
and attenuation states.

The attenuator integrates an inverter to allow a
single control for series/shunt attenuation. Inverter
requires a -5 V supply (VCC) and 17 mA typical, logic
is 0 V / +5 V.
The device is also available in a lead-free 3 mm
16-lead PQFN plastic package; order part number
MAAD-011021-TR0500.

Applications Section
Application Information
Mounting and Bonding Techniques
The MAAD-011021 is designed for extremely wide
band and robust attenuation applications. It uses a
combination of series and shunt cold channel,
multiple-gate FETs to achieve high linearity and
accurate attenuation repeatability. We recommend
using double bonds at both RF input and output, as
well as keeping bondwires as short as possible to
ensure higher frequency operation. This part is the
most accurate for X-band applications.
The Monolithic Circuit is designed for robust and
reliable usage. The die features complete
passivation on all critical areas as well as a
protective BCB die coat.
The die should be attached directly to the ground
plane with silver conductive epoxy for best results.
A true 50 Ω microstrip or co-planar waveguide is
recommended for bringing RF to and from the die
as shown in the demonstration board below. This
board uses 0.200 mm (8 mils) Rogers 4350 as the
top dielectric layer.
The MAAD-011021 has a built in inverter function
which allows a single +5 V / 0 V single control for
each bit. This is useful if you require very fast
switching times and have +5 V / 0 V available.
Alternatively one can mount the die directly to the
ground plane and launch with microstrip substrates
in either alumina or Rogers to the same level as
the top of the die, allowing for shorter bond wires.
The MAAD-011021 is DC-coupled at both RFIN and
RFOUT. If operation at DC is desired, 0 Ω jumpers
(or continuous 50 Ω RF lines) should be used in
series with RFIN and RFOUT. Customer should take
extra care to ensure that the voltage at both RFIN
and RFOUT are 0 V; excess voltage can damage the
part. If operation at DC is not required, simply use
series blocking capacitors.
The RF input and output pads are DC coupled.
Blocking capacitors are required if there is a DC
potential on either port.
