Designer Kits

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has released the industry's lowest power and smallest form factor SMT packaged Optical Modulator Driver, which operates from DC to 30 GHz, and is designed for 40 Gbps and 100 Gbps Mach-Zehnder optical modulator driver applications.

The HMC5850BG features high gain across a wide frequency range, low power dissipation, very compact size, integrated peak detector function, fast rise/fall time and integrated bias-tee inductor. The driver provides 8 Vp-p saturated output swing up to 32 Gbps and features output swing cross point adjustment. With a wide supply operating range from +5V to +7V, the HMC5850BG is an environmentally friendly product consuming only 1 Watt of power. The HMC5850BG provides Long Haul system designers with scalable power dissipation for varying output drive requirements. The integrated peak detector function enables monitoring and maintains a constant output swing from the modulator driver. Integrated high speed bias-tee eliminates the requirement for external components. The HMC5850BG can also interface with the HMC981LP3E active bias controller, enabling stability of performance over operating conditions.

The HMC5850BG operates between the -40 °C 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 Vp-p to 8 Vp-p.

The HMC5850BG features RF I/Os that are internally matched to 50 Ohms, and are housed in 9.75mm x 6mm x 3.29 mm laminate substrate based BGA surface-mount package. The package comes with an ESD protection feature. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
