| High speed logic and data systems are extremely challenging to develop. They require an intimate knowledge of both digital and analog signals, frequency and time domain, SiGe IC design and high speed packaging. This is why Marki has partnered with ADSANTEC, a high-speed mixed signal IC design house, to create the MUX-56 2:1 Multiplexer. |  |
By integrating the ASNT5153 multiplexer chip into a custom designed high speed/high fidelity module, the MUX-56 is capable of creating high speed signals up to 56 Gb/s from two lower speed signals. Alternatively MUX-56 can be operated as a switch with DC biases or a low frequency clock input. When operated as a switch the input data rate of each channel can be as high as 40 Gb/s. Although natively differential on all ports (clock, data inputs, and data output), the MUX-56 can be operated single ended by terminating the unused output port in a 50 ohm load. All ports are internally terminated to 50 ohms. The MUX-56 is the first in a series of modules in development using ASNT chips.
Low LO Drive Passive GaAs MMIC Double Balanced Mixers
One of the key challenges in integrating a mixer into an RF system is the available LO power. Available LO power dictates a mixer's ability to "turn on" and insufficient available LO power will degrade isolation,conversion loss, and spurious performance. SWAP considerations and amplifier limitations in millimeter bands can limit available system LO power.
To overcome this challenge, Marki Microwave is proud to announce two additional entries into our growing line of MMIC mixers; the MM1-0320L and MM1-1857L.

The MM1-0320L and MM1-1857L are both low LO drive mixers. They require LO powers as low as +5dBm and +7dBm respectively. Combined, both mixers support an operating range of 3 to 57 GHz and allows access to most useable RF operating bands. The MM1-0320L and MM1-1857L give system designers and integrators the unique trade-off of using lower LO power, for a small hit to mixer non-linearity, while preserving linear specifications such as conversion loss and LO-RF isolation.
