Description
Up to 6 GHz Medium Power Silicon Bipolar Transistor Chip Technical Data AT-42000 .
Hewlett-Packard’s AT-42000 is a general purpose NPN bipolar transistor chip that offers excellent high frequency performance.
Features
* High Output Power: 21.0 dBm Typical P1 dB at 2.0␣ GHz 20.5 dBm Typical P1 dB at 4.0␣ GHz
* High Gain at 1 dB Compression: 15.0 dB Typical G1 dB at 2.0␣ GHz 10.0 dB Typical G1 dB at 4.0␣ GHz
* Low Noise Figure: 1.9 dB Typical NFO at 2.0 GHz
* High Gain-Bandwidth Prod
Applications
* in the VHF, UHF, and microwave frequencies. An optimum noise match near 50 Ω up to 1 GHz , makes this device easy to use as a low noise amplifier. The AT-42000 bipolar transistor is fabricated using Hewlett-Packard’s 10 GHz fT Self-Aligned-Transistor (SAT) process. The die is nitride passivated for
