Learn More About Amplifiers

ADM series amplifiers are GaAs pHEMT distributed amplifiers designed and optimized to drive Marki Microwave mixers. A combination of high output power and efficient power dissipation make the ADM series ideal for driving amplifiers H, I, and S diode Marki mixers and multipliers. Strong odd (3rd and 5th) output harmonics make the ADM-0026-5929SM amplifier an ideal choice as a square wave LO generator for T3 style mixers. For general purpose small-signal applications that do not require strong square wave generation, the ADM-0126-5838SM and ADM-0026-5931SM can be used. All ADM amplifiers are available as bare die and industry standard 3x3mm or 4x4mm QFN packages. Multi-chip connectorized modules are also available.

LO Driver Surface Mount

Surface mount LO driver amplifiers are designed to function as the final output stage of the LO signal chain. Marki LO amplifiers provide a high power, fast rise time signal for driving a mixer’s LO port. Surface mount LO driver amplifiers  simplify system design by providing sufficient LO power to achieve the desired mixer spurious suppression, IP3, and other critical non-linear specifications. All ADM series amplifiers are available in a standard QFN package with broadband die versions available upon request.

LO Driver Bare Die/Modules

Marki LO driver amplifiers offer high performance and convenient operation as bare die or connectorized modules.
Our bare die amplifiers offer extremely flat gain across broad bandwidths without any requirement for negative supply sequencing. They are optimized to provide odd harmonic generation to maximize the linearity of our T3 and MT3 mixers.
These die are available as well in the ADM series of LO driver amplifier modules, which come with bias tees, blocking capacitors, and bypass capacitors in a convenient small form factor. Additionally Marki offers millimeter wave LO driver amplifiers up to 50 GHz.
