Norden Millimeter has developed an 18 to 40 GHz down converter with an integrated 0.5 to 18 GHz bypass path for combining both into a single 0.5 to
18 GHz IF output. Conversion gain is 12 dB (± 3 dB) typical, noise figure is 14 dB typical and VSWR IF/LO/RF is 2.5:1 typical. Norden uses a variety of technologies to miniaturize multiple functions into a single small housing running off a single power supply voltage to minimize size, weight and power. These are designed for the ELINT and EW markets.
In addition, Norden Millimeter has developed a 0.5 to 18 GHz receiver for the ELINT market. The frequency range of this receiver can also be extended by using Norden’s 18 to 26.5 GHz and 26.5 to 40 GHz block down converters. The noise figure is 14 dB typical with an IF of 1 GHz ± 250 MHz. Image rejection is 85 dBc typical, IF rejection is greater than 100 dBc typical and spurs/harmonics at −15 dBm input are 60 dBc typical. The receiver is highly channelized for increased interference immunity. To minimize the power consumption of the receiver, the unselected bands are turned off. Norden uses the latest MMIC and packaging technology to bring this design to manufacturing in an extremely small package size.
Norden Millimeter has extensive experience in design and manufacturing of frequency converter products for both the commercial and military markets. Norden understands that the vast majority of requirements for converter products involve custom design and packaging, custom LO and IF frequency selection, conversion gain and linearity requirements. To this extent, it is difficult to develop a useful line of “standard” converter products. Consequently, Norden recognizes that the majority of requirements for these products will be per individual customer specifications.
