Transcription

1 Advance Product Overview Features: DC to 12GHz Frequency Range 25 Watt (CW), 150W (Pulsed) Max Power Handling Low On-State Insertion Loss < GHz High-linearity, IIP3 > 85dBm -25dB 6GHz Maximum voltage (AC or DC): +300 Volt on RF Input < 10us On/Off Switching Time High Reliability > 3 Billion Switching Operations Integrated Analog Gate Control w/hv Boost Hermetic 4mm x 4mm QFN Package Applications: Switched filter banks and tunable filters High power RF front ends (TX/RX) Low-loss switch matrices RF EM relay replacement Markets: Defense and Aerospace Test and Measurement Systems Wireless Infrastructure Description: The MM5120 is a high-power micro-mechanical switch offered by Menlo Micro, which has developed a new Digital-Micro-Switch (DMS) fabrication process and applied it to DC and RF/microwave switch applications. The innovative DMS technology enables highly reliable micro-mechanical switches capable of > 25 watts in a very small SMT package. The MM5120 provides ultra-low insertion loss and superior linearity from 12GHz down to DC, with greater than 3 billion switching cycles guaranteed at elevated +85ºC temperatures. An integrated analog gate controller allows the user the option to provide the required high-voltage gate signal externally, or to generate it internally. The MM5120 is an ideal solution for replacing bulky and less reliable RF electromechanical relays, as well as RF/microwave solid-state switches where linearity and insertion loss are critical parameters.

4 Modes of operation The MM5120 allows the user to provide the 70V gate bias required to drive the switch externally, or to have the MM5120 create the 70V gate bias internally through a dedicated boost circuit. If using external 70V: VDDHV = high voltage supply 70V max VBST = DO NOT CONNECT VDD = 3.3V If using internal 70V: VDDHV = DO NOT CONNECT VBST = inductor between VBST and VDD VDD = 3.3V (inductor between VBST and VDD) The MM5120 allows the user to provide a 3V gate control signal required to turn the switch on and off, or to provide an alternate gate control signal which can be at any voltage from 3V to 10V. If using VDD 3V: VDD = 3V VDD10 = tie to VDD If using VDD10 (3V to 10V gate control signal): VDD = NO CONNECT VDD10 = desired gate voltage Page 4 Doc Rev. MM5120 v0.7 PRELIMINARY
