Description
The M/A-COM MAAPSM0015 is a medium power
wideband AGC amplifier that typically provides 11 dB
of gain with 25 dB of AGC range. The circuit topology
is a six-section traveling wave amplifier using common
source FETs which provide very wide bandwidth.
Typical input and output return loss is 12 dB. RF ports
are DC coupled, enabling the user to customize sys-
tem corner frequencies. DC bias can be provided
through the drain termination resistor without the need
for an external bias inductor. For higher power appli-
cations, an external inductor can be used to bias the
amplifier through the RFout or Vd_aux pads. Applica-
tions include OC-192 12.5 GBit/s receive AGC ampli-
fier and lithium niobate Mach-Zehnder modulator driver
amplifer.
The MAAPSM0015 requires off-chip decoupling and
blocking components. Each device is 100% DC and
RF tested on wafer to ensure performance compliance.
The device is provided in chip form. M/A-Com fabri-
cates the MAAPSM0015 using a 0.5 µm gate length
low noise multi-function self aligned gate (MSAG)
MESFET process. This process features silicon nitride
passivation and polimide scratch protection. The die
thickness is 0.003”.
