Incoming data packets from a DUT are monitored to discern between data packets transmitted as part of a DUT calibration cycle or initial data packets being transmitted as the DUT transmitter circuitry settles at its new settings (e.g., transmit signal frequency or power), and later data packets transmitted following completion of the DUT calibration cycle or settling of the DUT transmitter circuitry. Following identification of these later data packets, the tester is so notified and begins the test procedure, e.g., capturing the data packets for analysis. Meanwhile, the tester has been allowed to remain in active use for other test purposes during DUT calibration cycles and settling intervals, thereby increasing testing efficiency and reducing overall test time. |

We disclose an optical receiver that can receive PDM-QDB and PDM-QPSK signals without hardware changes. In an example embodiment, the optical receiver includes a MIMO equalizer configured to perform electronic polarization de-multiplexing and ISI compensation. The constant modulus algorithm that controls the configuration of the MIMO equalizer also causes the MIMO equalizer to output signal samples corresponding to the QPSK modulation format regardless of whether the received optical signal is QDB-modulated or QPSK-modulated. A QPSK-to-QDB constellation converter processes the signal samples generated by the MIMO equalizer to convert them into the QDB modulation format. A QDB decoder coupled to the constellation converter then recovers the data encoded in the received optical signal by mapping the processed signal samples onto the QDB constellation. Differential encoding used at the corresponding remote transmitter enables the decoder to correctly recover the encoded data both when the received optical signal is QDB-modulated and QPSK-modulated. |

Optical transmitter
A photodiode converts an optical signal output from a laser diode to a current signal, and a current-to-voltage conversion circuit converts the current signal to a voltage signal. A comparison amplifier compares the voltage signal with a reference voltage to control the current flowing from a variable current source and increases or decreases a bias current for driving the laser diode. The current-to-voltage conversion circuit comprises a resistor and a variable current source that are connected in parallel. Therefore, it is possible to change the bias current without changing the resistance value of the resistor and to avoid limiting the dynamic range of the optical signal that is output. In addition, since the resistance value of the resistor does not change, the loop gain does not change, thereby stabilizing the control operation. |

Inverse class F amplifiers with intrinsic capacitance compensation
The embodiments described herein provide inverse class F (class F−1) amplifiers. In general, the inverse class F amplifiers are implemented with a transistor, an output inductance and a transmission line configured to approximate inverse class F voltage and current output waveforms by compensating the effects of the transistor's intrinsic output capacitance for some even harmonic signals while providing a low impedance for some odd harmonic signals.

Devices including, methods using, and compositions of reflowable getters
Methods for protecting circuit device materials, optoelectronic devices, and caps using a reflowable getter are described. The methods, devices and caps provide advantages because they enable modification of the shape and activity of the getter after sealing of the device. Some embodiments of the invention provide a solid composition comprising a reactive material and a phase changing material. The combination of the reactive material and phase changing material is placed in the cavity of an electronic device. After sealing the device by conventional means (epoxy seal for example), the device is subjected to thermal or electromagnetic energy so that the phase changing material becomes liquid, and consequently: exposes the reactive material to the atmosphere of the cavity, distributes the getter more equally within the cavity, and provides enhanced protection of sensitive parts of the device by flowing onto and covering these parts, with a thin layer of material. |
