Description
The TriQuint TGA4805-EPU is a
wideband transimpedance amplifier with
differential outputs that provides 500 Ohm
single-ended transimpedance into a
50 Ohm termination (1000 Ohm
differential into a 100 Ohm termination).
Typical output return loss is > 15 dB and
the average equivalent input noise current
is 9 pA/
Hz (1 GHz to 10 GHz). Typical
3dB BW is 30 KHz to 11GHz with 0.2 pF
of photodiode capacitance.
The TGA4805 operates from a single +5V
supply typically dissipating 225mW of DC
power. The device is backside grounded
with vias and requires no grounding bond
wires.
The TGA4805 requires off-chip decoupling
and the RF ports are DC coupled. Each
device is 100% RF tested on-wafer to
ensure performance compliance. The
device is available in die form.
