High RF Power Output
The QPB0618J is a solid state driver amplifier based on GaN MMIC technology, with an operating range of 2 - 18 GHz with a saturated output power of 45 dBm (32 Watts). Its compact size and weight allow it to be used to drive a number of Spatium power amplifiers in microwave high power transmitters for EW and radar applications.
Planar multistage driver module for use with existing Spatium platforms operating in the 2 - 18 GHz frequency band. A variable attenuator in conjunction with a temperature sensor compensates for variation in gain over the operating temperature range. Gate bias and variable attenuator settings are digitally progarmmable using non-volatile I2C digital potentiometers. RF input and output are via SMA connectors. DC and control interface is provided via a Micro D-Sub connector.
The QPB0618J includes a DC enable function that can switch off the MMIC amplifiers to put the unit in low power consumption state. Users can use this mode for RF pulsing operation.
