<strong>APD</strong> <strong>Photoreceivers</strong><br />
<strong>Voxtel</strong>’s line of <strong>APD</strong> photoreceivers achieve industry-leading sensitivity with bandwidth ranging from the MHz<br />
to GHz scales. These receivers are hermetically sealed in TO-8 and TO-46 packages, and integrate a <strong>Voxtel</strong> <strong>APD</strong><br />
with a transimpedance amplifier (TIA) to provide wideband, low-noise preamplification of signal current from<br />
the <strong>APD</strong>. The <strong>APD</strong> and TIA are integrated on a ceramic submount, lowering parasitic capacitance and thereby<br />
maximizing bandwidth and minimizing noise.<br />
The receivers integrate a calibrated temperature sensor, capacitive decoupling, separate package and circuit<br />
grounding, and include differential output to allow users easy integration into their system electronics.<br />
<strong>Photoreceivers</strong> in TO-8 packages also include thermoelectric cooling to stabilize the <strong>APD</strong> gain over the range<br />
of application environments.<br />
