Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure
to absolute ratings for extended periods of time may adversely affect
reliability.
Notes:
1. Pins 3 and 6 should be AC-coupled. No external DC bias should be

Notes:
(1) Measured performance of MMIC alone. Balun effects de-imbedded from measurement.
(2) Measured with a balun on input and output of the device. See Figure 3 for test setup.
(3) All parts measured with 110 channel flat input. Parts A and C measured at +34 dBmV output (per channel).
Parts B and D measured at +44 dBmV output (per channel).
(4) A fixed resistor is needed for parts A through C; part D does not need an external resistor (see Table 6.)
These resistors set the devices' current draw. Bias voltage is +12 VDC.
