The monolithic microwave integrated circuit (MMIC) products include four wideband low noise MMIC amplifiers (MMA040AA , MMA041AA, MMA043AA and MMA044AA) and two wideband gallium arsenide (GaAs) MMIC switches (MMS006AA and MMS008AA). These high linearity MMIC amplifiers and switches, Microsemi says, represent affordable,low-risk solutions that can reduce end-equipment bill of materials costs.
Microsemi’s new devices are suitable for of applications within the defence and industrial markets, including receiver front end amplifiers for electronic warfare (EW) and signal intelligence (SIGINT); and wideband bench top and portable measurement equipment up to 26 GHz. The amplifiers offer flat gain over a wide frequency range, and significantly better output third-order intercept point (OIP3) performance [than available devices]. The GaAs MMIC switches provide broad frequency coverage combined with superior insertion loss, isolation and input third-order intercept point (IIP3) performance.
The MMA040AA, a DC to 28 GHz distributed low noise amplifier, features a low noise figure of 2.5 dB, flat gain of 16 dB and provides 27 dBm of OIP3 linearity. The MMA041AA, a DC to 26 GHz distributed low noise amplifier, features 3.2 dB noise figure, 18 dB gain and 35 dBm of OIP3 linearity. The MMA043AA, a 0.5 to 12 GHz low noise amplifier, offers a 1.4 dB noise figure, 16.5 dB of gain and 29 dBm of OIP3 linearity. The MMA044AA low noise amplifier operates across the 6 to 18 GHz band and provides a low noise figure of 1.7 dB, in combination with 21 dB of gain and 30 dBm of OIP3 linearity.
The MMS006AA (diagram, above), a DC to 20 GHz single pole double throw (SPDT), non-reflective MMIC switch, features isolation of 45 dB and low insertion loss of 1.5 dB at 15 GHz. The MMS008AA is a DC to 8 GHz single pole four throw (SP4T), non-reflective MMIC switch that offers over 45 dB of isolation and less than 1.7 dB insertion loss. Both devices handle up to 30 dBm of input power and offer high input third-order intercept performance of 42 dBm and 46 dBm respectively. All six MMIC devices feature radio frequency (RF) ports that are internally matched to 50 Ohms and are available in bare die, which facilitates easy integration into multi-chip modules (MCMs).
