1. At IMS, Menlo Micro demonstrated how its MM5130 SP4T switch still performs when driven by a high-power signal.
Looking at its specifications, the MM5130 micro-mechanical SP4T switch operates from dc to 18 GHz. The device can handle 25 W of continuous-wave (CW) power along with 150 W of pulsed power. At 6 GHz, the MM5130 achieves an insertion loss of 0.2 dB. In addition, the switch’s third-order input intercept point (IIP3) is in excess of +85 dBm, and it achieves 25 dB of isolation at 6 GHz.
According to Menlo Micro, the MM5130 is rated for more than 3 billion switching cycles at +85°C. The device comes in a 2.5- × 2.5-mm wafer-level chip-scale package (WLCSP). Markets for the MM5130 include aerospace and defense, test-and-measurement systems, and wireless infrastructure.
Menlo Micro’s other new high-power SP4T micro-mechanical switch is the MM5120. This device covers a frequency range of dc to 12 GHz. At 6 GHz, the MM5120 is also rated for 25 W of continuous-wave (CW) power and 150 W of pulsed power. Furthermore, the switch achieves 0.35 dB of insertion loss at 6 GHz. The MM5120 comes in a 4.0- × 4.0-mm BGA package.
Skyworks also showcased its latest RF switching products at IMS. On the show floor, the company demonstrated its SKY12245-492LF 100-W single-pole, double-throw (SPDT) switch with integrated driver circuitry (Fig. 2). The SKY12245-492LF covers a frequency range of 300 MHz to 3.8 GHz. It requires only a single +5-V dc supply and a control voltage that ranges from 0 to 3 V. Intended for LTE time-division-duplex (TDD) applications, the device comes in a 5.0- × 5.0-mm quad-flat no-leads (QFN) package.
