1) OIP3 and OIP2 are measured with two tones at an output power of +10 dBm/tone separated by 6 MHz.
2) OIP2 is measured at F1+F2 Frequency.
3) CSO & CTB was measured at 335.25 MHz.
For 116 flat channels at the input, measured at the output were 77 analog channels (55 MHz to 550 MHz) @ +20 dBmV per channel
and 39 digital channels (550 MHz to 750 MHz) @ 6 dB lower than that of the analog channel.

Note: 1. Backside metal paddle is RF and DC ground.
Mounting Recommendation (in mm)
Note: 1. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
2. To ensure reliable operation, device ground paddle-to-ground
pad soldering is critical.
3. Add mounting screws near the part to fasten the board to a
heat sinker. Ensure that the ground / thermal via region contacts the heat sinker.
4. A proper heat dissipation path underneath the area of the
PCB for the mounted device is strictly required for proper
thermal operation. Damage to the device can result from inappropriate heat dissipation.
