Low noise amps cover wide and narrow bands

Labtech continues to expand its microwave amplifier product offering to meet the growing demand from the satellite communication and the UAV market.

Labtech Microwave's LMA and LMB branded series are linear low noise broadband and narrow-bandwidth limiting amplifiers, respectively.

The LMA006 to 009 have been designed to include all parasitic elements, thus enabling excellent gain flatness performance combined with good noise and output power.

The LMA009, for example, operating over the frequency range 2-18GHz, incorporates gain slope correction for system integration applications.

The gain slope is required to overcome losses in systems where there are varying lengths of RF (radio frequency) cables.

In addition, the LMA009 automatically compensates for heat fluctuations, ensuring the gain level is constant over a wide temperature range.

The LMB004 to 006 units, suitable for TWT (travelling wave amplifier tube) driver applications, have a number of features, including optimum gain level to ensure that the wide input power window is compressed into the narrow output power window over all the specified temperature conditions.

In particular, the LMB005 includes an electronically controllable attenuator which sets the output power to the exact level required within the range specified.

The units are lightweight, hermetically sealed, includes integral voltage regulation, are RoHS compliant and suitable for use in military environments.

Commenting on the new products, Robert Lowther, Sales and Marketing Director at Labtech Microwave said: "Labtech continues to expand its microwave amplifier product offering to meet the growing demand from the satellite communication and the UAV (unmanned aerial vehicle) market where their use creates a demand for Labtech's proven expertise in producing TWT driver amplifiers".
