Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | DC and RF Ground is provided through the backside of the die. |  |
| NC | Non-connect (NC) | Do not connect to or ground these pads. Leave them floating for normal operation. | - |
| RF In | RF Input | This is the amplifiers RF input port. It is internally matched to 50 Ohms and is internally DC blocked. |  |
| RF Out | RF Output | This is the amplifiers RF output port. This port is internally matched to 50 Ohms and is internally DC blocked. | |
| Vb | Positive Bias Pin | This is the positive DC bias voltage for the amplifier IC. The voltage at this pin controls the current draw Id of the part. Higher voltage results in higher current. For normal operation, the voltage at this pin is adjusted to produce an Id of 60mA when Vd=6V. Alternatively, it is possible to use a single positive voltage supply and a 751Ohm resistor between Vd and Vb pins. This part requires off-chip bypass capacitors of 100pF and 0.1uF installed at this pin as close to the IC as possible. See applications circuit. |  |
| Vd | Positive DC Supply Voltage | This is the positive DC supply voltage for the amplifier IC. This pin is nominally set to +6V. This part requires off-chip bypass capacitors of 100pF and 0.1uF installed at this pin as close to the IC as possible. See applications circuit. |  |

Absolute Maximum Ratings
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If any one of these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device.

|---|---|---|
| Bias Supply Voltage (Vb) | 6.5 | V |
| Drain Current (Id) (No RF Applied) | 85 | mA |
| Maximum Operating Temperature for MTTF > 1E6 hours | 85 | °C |
| Maximum Storage Temperature | 125 | °C |
