The HMC7282B is a four channel optical modulator driver amplifier module and is ideal for driving external mach-zender modulators in 100Gbps DP-QPDK applications.

The HMC7282B is compliant with OIF's (Optical Interface Forum) "Integrated Polarization Multiplexed Quadrature Modulated Transmitters Implementation Agreement" and is hermetically sealed to meet stringent quality requirements of the fiber optic systems.

The HMC7282B is a highly integrated connectorized module with 50ohm matched AC coupled RF inputs and outputs. The RF output ports are designed to withstand up to 50V DC bias voltages relative to the supply voltage in order to support varying modulator bias conditions. The supply and control voltage pins are equipped with internal de-coupling capacitors and a discrete isolated diode is incorporated in the module for temperature monitoring.

The HMC7282B can operate up to 32Gbps and delivers up to 8Vpp output signal swing, exhibiting less than 0.25psec additive jitter and ±5psec group delay variation.

The HMC7282B operate on a wide supply range from 5V to 8V and features scalable power dissipation for varying output drive requirements. The HMC7282B consumes less than 4.5W and 5.5W, for 6.5Vpp and 7.5Vpp output voltage swing levels, respectively.

The output signal amplitude and cross-point are adjustable for each channel separately through the control pins to optimize the specific aspects of the driver characteristics for required optical performance.
