Differential switch routes high-frequency signals
The MM5600 DPDT switch from Menlo Micro routes signals to 20 GHz, 40 Gb/sec.
5G is one of the technologies driving the need for higher-speed digital and RF signals. Those signals, which often run over differential pairs through a PCB, typically need switching. MEMS switches offer fast switching speeds with low power and low signal loss. Menlo Micro’s MEMS-based MM5600 can handle RF signals to 20 GHz and high-speed digital signals to 40 Gb/sec (with PAM4 modulation).
Housed in an 8 mm × 8 mm land grid array (LGA) package, the MM5600 DPDT switch (datasheet) features RON of 1.2 Ω. Insertion loss is 2.5 dB with 6 dB return loss, both at 12 GHz.
Applications include test and measurement load boards and serial high-speed memory designs.
Maximum switching time is 15 µsec (on) and 5 µsec (off). “A typical load board in and automated test system contains 64 or 128 DPDT switches,” said Chris Giovanniello, Menlo Micro co-founder and SVP marketing to 5G Technology World. “Switching times has a direct effect on total test time, making short switching time’s important.”
The MM5600 includes driver circuits controlled through an 8-bit serial interface. A shift register converts the serial stream to parallel. The integrated driver requires and 89 VDC bias voltage, VBB.
