2Max. RF Input Limit must be further limited if input VSWR > 2.5:1

3Users should avoid exceeding 80% of 2 or more Limits simultaneously

Notes:

•

Operating conditions that exceed the Absolute Maximum Ratings will result in permanent damage to the device.

•

Total Power Dissipation defined as: PTOT ≡ (PDC + PIN) – POUT, where:

PDC: DC Bias Power

PIN: RF Input Power

POUT: RF Output Power

•

Total Power Dissipation to be de-rated as follows above 22

°C:

PTOT= 3.5 - (0.04W/°C) x TPACK

where TPACK = source tab lead temperature above 22°C

(coefficient of de-rating formula is the Thermal Conductivity)

Example: For a 55

°C source lead temperature: PTOT = 6.0 - (0.04 x (55 – 22)) = 4.68W

•

For optimum heatsinking, metal-filled through (Source) via holes should be used directly below the central

metallized ground pad on the bottom of the package.

•

Note on Thermal Resistivity: The nominal value of 25

°C/W is measured with the package mounted on a large

heatsink with thermal compound to ensure adequate (unsoldered) contact. The package temperature is referred to

the Source leads.

HANDLING PRECAUTIONS

To avoid damage to the devices care should be exercised during handling. Proper Electrostatic

Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and

testing. This product has be tested to Class 1A (> 250V but < 500V) using JESD22 A114, Human

Body Model, and to Class A, (< 200V) using JESD22 A115, Machine Model.
