Teledyne Microwave amplifiers are generally balanced designs-except the 2.0- 18.0 GHz which is a distributed design all of which are manufactured with MIC technology. The GaAs FETs used in these amplifiers are proven devices.

The specification table shows excellent noise figures which can be improved for narrow-band applications where required.

Teledyne Microwave also offers other functions for amplifiers in this frequency range such as: phase and gain matching, input limiters, output limiters and log amplifiers. See the specification sheet on Teledyne’s connectorless (drop-in) packages for amplifiers in this frequency range.

With Custom Teledyne Devices

In 2011 Teledyne Microwave has investing in a new range of LNA products specifically designed for the communications EW market. With an internally designed MMIC using our own fab we are now able to offer one of the best noise figures available on the market.

A typical example of this is our new K-Band LNA. This model operates over 20.2 GHz - 21.2 GHz with 1.4 dB Noise Figure at 25°C and has an integrated WR42 Waveguide output and K(f) Connector input. The aluminum alloy housing is environmentally sealed and also fully EMI shielded. The waveguide cavity is also sealed to support up to 15 psi. The waveguide flange can incorporate tapped or through holes with available configurations including choke, grooved, and cover. The low-noise amplifier is lightweight and has a small profile and footprint. LNA includes reverse voltage protection and full internal regulation. The unit has a typical noise figure of 2.0 dB and a P1dB of 17 dBm. Output IP3 is 20 dBm minimum. Small-signal gain is 40 dB and gain flatness is ±1 dB maximum. Current draw is nominally 180 mA from a single +15V supply, with an operating temperature of -54 to +85°C case.
