Landwehr
Electronic GmbH, one of the leading companies for the development
and production of high speed radio frequency (rf) drivers, is
expanding its range with the A 27x low power series. The Q-Switch driver has been especially designed for acousto-optic miniature or compressional mode Q-Switch applications. The A 27x belongs to the Q-Switch Driver generation which allows Laser Pulse Control (LPC) by running Active Gain Control (AGC from DC to 350 MHz) of the linear preamplifier. There is no need any more to use nonlinear diode modulators, switched oscillators or a programmed attenuator to achieve a first pulse suppression or similar function. With Laser Pulse Control there are no restrictions. |

The
rf power output follows any kind of modulation because high speed
switching over gain control has now become realistic. Feel free
and use this driver with any synchronized mode of analogue or
digital modulation. The high technical performance guarantees
stable power output, best linearity of rf output vs input control
voltage, superb switching characteristics and exceptional on/off
ratio. Furthermore, a preadjustable SWR protection and an overheat
indication have been integrated. The AO Q-Switch Driver can be supplied for different supply voltages which guarantees minimum power dissipation in relation to the required radio frequency output signal. |
