2 / 16 page 2 ALM-38140 Absolute Maximum Rating [1] TA = 25°C Symbol Parameter Unit Absolute Maximum Isupply, max Supply Current mA 18.0 Icontrol, max Control Current mA 33.4 Pin, max RF Input Power dBm 27dBm CW, 36dBm with 12.5% duty cycle Pdiss Total Power Dissipation W 0.3 Tj Junction Temperature °C 150 Tstg Storage Temperature °C -60 to 150 Thermal Resistance [2] θjc = 106.3°C/W (Vc = 1V, Vsupply = 2.7V, Tc = 85°C) Notes: 1. Operation in excess of any one of these limits may result in permanent damage to the device. 2. Thermal resistance is measured from junction to case using Infra-Red method. Electrical Specifications, Vsupply = 2.7V, TA = 25°C, Z0 = 50Ω Symbol Parameter and Test Condition Frequency (MHz) Unit Min Typ Max Isupply Supply Current drain (Vcontrol = 1V) mA – 2.5 – Icontrol Control Current drain (Vcontrol = 5V) mA – 20.5 – S21 Maximum Attenuation (Vcontrol = 1V) 900 dB – 42.0 – S21 Maximum Attenuation (Vcontrol = 1V) 1900 dB 36.0 39.0 – S21 Insertion Loss (Vcontrol = 5V) 900 dB – 2.8 – S21 Insertion Loss (Vcontrol = 5V) 1900 dB – 3.2 3.7 Dynamic Range 900 dB – 38 – Dynamic Range 1900 dB 33 36.5 – IRL Input Return Loss (Vcontrol = 5V) 1900 dB 10 14.5 – ORL Output Return Loss (Vcontrol = 5V) 1900 dB 10 13.5 – IIP3 [5] Input Third Order Intercept Point 900 dBm – 50 – IIP3 [5] Input Third Order Intercept Point 1900 dBm – 50 – IP1dB [6] Input Power at P1dB Compression (Vcontrol = 5V) 900 dBm – 32 – IP1dB [6] Input Power at P1dB Compression (Vcontrol = 5V) 1900 dBm – 33 – Phase Shift (Vcontrol = 1V) 1900 degrees – 10.5 – Notes: 4. Data above is obtained using demo board shown in Figure 32 and 33. 5. 2-tone IIP3 test condition: FRF1, FRF2 = 1.1MHz separation, Input power = 22dBm 6. IP1dB measured with 12.5% duty cycle. 7. The performance above obtained with phase compensation inductor value based on the table 1 below. 8. Use proper biasing, heat sink and de-rating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and application note (if applicable) for more details. |
