Rx mode Thermal Resistance [2]
LNA1: Vdd1 = 5.0 V, Idd1 = 50 mA
LNA2: Vdd2 = 5.0 V, Idd2 = 120 mA;
LNA1 jc = 72.4°C/W
LNA2 jc = 65.0°C/W
Tx mode Thermal Resistance [2]
LNA1: Vdd1 = 5.0 V, Idd1 = 50 mA
LNA2: Vdd2 = 5.0 V, Idd2 = 120 mA;
jc = 11.7°C/W
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 in Rx mode with both LNA1
and LNA2 turned on. Board temperature TB is
25° C.
LNA1: Derate at 14 mW/°C for TB > 114° C.
LNA2: Derate at 15.6 mW/°C for TB > 92° C.
4. Switch Turn On Condition:
Tx mode: Vbias = 5 V, Vc1 = 0 V, Vc2 = 28 V
Rx mode: Vbias = 5 V, Vc1 = 28 V, Vc2 = 0 V
