*Waveguide amplifiers must be connected to thermally grounded waveguide prior to biasing.
**He Fan Assembly only included on select amplifiers. Can be removed, but user must provide sufficient heatsinking to stay below the maximum case
temperature.
†All amplifiers will meet P1dB specification listed above. P1dB data will not be provided with each amplifier.
*For SMP Bias Connectors Only: An SMP to LEMO 00 cable or SMP to SMA cable or both can be provided. Must be specified on quote or PO. An SMP to
LEMO 00 cable is provided if a VDI Waveguide Amplifier is purchased with VDI SAX-UP, CCU, or CCD modules. SMP to LEMO 00 cable is for compatibility
with VDI SAX-UP, CCU and CCD modules. SMP to SMA cable is for general use.
