Optical modulator driver offers lowest power, form factor

Ideal for 40 Gbit/s and 100 Gbit/s Mach-Zehnder optical modulator driver applications, the HMC5850BG driver amplifier is offered as the industry’s lowest power (at 1 W) and smallest form factor SMT packaged (59 mm2). Additional features include a wide operating range from 5 to 7 V, an integrated peak detector function, and RF I/Os that are internally matched to 50 Ω.

Housed in a laminate substrate based BGA surface-mount package, the HMC5850BG operates between the –40° to 85°C temperature range, provides up to 32 dB of gain, and exhibits very low additive rms jitter of 230 fs and supports up to 32 Gbps operation. The output swing is adjustable from 5 to 8 Vp-p.

There are only 4 dc control signals required to tune the crossing and output RF amplitude. The integrated bias-tee eliminates the need for external high frequency coil, simplifies the PCB design and lowers the BOM cost. (Contact company for pricing and availability)

Hittite Microwave (HITT) designs and develops high performance integrated circuits, modules and subsystems for demanding RF (RF) microwave and millimeter wave applications. These applications include cellular, fiber and satellite communications, as well as medical and scientific imaging, industrial instrumentation, aerospace and defense electronics. With nearly 30 years of experience and innovative practices, Hittite has a strong presence in analog, digital and mixed-signal semiconductor technologies, ranging from device-level to complete subsystem design and assembly. Hittite Microwave was acquired and merged in 2014 by Analog Devices, Inc. (ADI).
