On-chip features include input and output AC coupling capacitors, an integrated bias inductor, an integrated temperature sensor, and an enable or disable pin (VENBL). The quiescent drain current (IDQ), which can be adjusted, is 55mA operating from a 3.3V supply voltage (VDD). Operation at 5V is also supported. The ADL8124 is fabricated on a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT) process. This device is housed in an RoHS-compliant, 2mm × 2mm, 8-lead LFCSP package and is specified for operation over an extended temperature range of −55°C to +125°C.
