(Vdd = 5.0 V, Idd = 35 mA per channel),

jc = 62°C/W per channel

Notes:

1. Operation of this device in excess of any of

these limits may cause permanent damage.

2. Thermal resistance measured using Infra-Red

Measurement Technique.

3. Power dissipation with unit turned on. Board

temperature TB is 25° C. Derate at 16 mW/°C

for TB > 119° C.

Electrical Specifications [1], [4]

RF performance at TA = 25° C, Vdd = 5 V, Rbias = 6.8 kOhm, 1.9 GHz, measured on demo board in Figure 5 with component

list in Table 1 for 1.9 GHz matching.

Notes:

1. Measurements at 1.9 GHz obtained using demo board described in Figure 1.

2. OIP3 test condition: FRF1 = 1.9 GHz, FRF2 = 1.901 GHz with input power of -10 dBm per tone.

3. For NF data, board losses of the input have not been de-embedded.

4. Use proper bias, heatsink and derating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and application

note for more details.
