PTH 31042 10 Watts, 1.9-2.0 GHz 50-Ohm Power Hybrid Description * The PTH 31042 is a 50-ohm power hybrid intended for applications requiring linear power amplification in the PCS frequency range. The part is designed to operate with 50-ohm source and load impedances and includes bias circuitry with temperature compensation. The design is intended to simplify system design and save space with an overall size of less than one square inch. * * * * * * Guaranteed Performance at 1.93 to 1.99 GHz, 28 V - Output Power = 12 Watts (P-1dB) Min - Power Gain = 11 dB Min - Efficiency = 40% Min @ P-1dB Rugged Hybrid Design High Single Stage Gain Excellent Linearity Input VSWR less than 1:5:1 Full Gold Metallization 100% Lot Traceability Typical Output Power vs. Input Power Output Power (Watts) 20 15 e 1042 f = 1.99 GHz 3 10 8955 3456 A-12 f = 1.96 GHz 5 VDD = 28 V f = 1.93 GHz IDQ = 225 mA 0 0 0.3 0.6 0.9 1.2 1.5 Input Power (Watts) Package A Performance Characteristics Parameter Symbol Min Typ Max Units Frequency Range VDD (Nom.) = 28, IDQ (Nominal) = 225 mA f 1930 -- 1990 MHz Power Gain VDD (Nom.) = 28, IDQ (Nominal) = 225 mA Gp 11 12.5 -- dB Output Power at 1 dB Compressed VDD (Nom.) = 28, IDQ (Nominal) = 225 mA P-1dB 12 16 -- W Input Return Loss VDD (Nom.) = 28, IDQ (Nominal) = 225 mA RL 14 19 -- dB Efficiency at P-1dB VDD (Nom.) = 28, IDQ (Nominal) = 225 mA h 40 48 -- % e 1 e PTH 31042 Maximum Ratings Parameter Symbol Value Unit Supply Voltage VDD 32 Vdc Bias Current IDQ 1000 mA TCASE 90 C PD TBD Watts Operating Temperature Total Device Dissipation at TCASE = 25C Above 25C derate by W/C Storage Temperature TSTG 125 C Typical Performance Output Power @ P-1dB vs. Supply Voltage Output Power @ P-1dB (Watts) Power Gain vs. Power Output 15 13 f = 1.93 GHz 12 f = 1.96 GHz 11 f = 1.99 GHz 10 IDQ = 225 mA VDD = 28 V 9 8 0 5 10 15 15 1.93 GHz 1.96 GHz 10 1.99 GHz 5 IDQ = 225 mA 0 20 20 22 26 28 16 f = 1.99 GHz VDD = 28 V 50 14 Gain (dB) IDQ = 225 mA 40 f = 1.96 GHz 30 0 Gain -4 12 VDD = 28 V -8 10 IDQ = 225 mA -12 8 -16 6 -20 4 20 f = 1.93 GHz 4 8 12 16 Return Loss 2 0 1860 10 0 30 Gain and Return Loss vs. Frequency Efficiency vs. Output Power 60 Efficiency (%) 24 Supply Voltage (Volts) Power Output (Watts) 20 -28 1910 1960 2010 Frequency (MHz) Output Power (W) 2 -24 -32 2060 Return Loss (dB) Power Gain (dB) 14 20 e PTH 31042 Intermodulation Distortion vs. Output Power Intermodulation Distortion vs. Output Power 0 -10 VDD = 28 V, IDQ = 225 mA -10 IDQ = 225 mA, VDD = 28 V -20 f1 = 1930.0 MHz, f2 = 1930.1 MHz -20 f1 = 1960.0 MHz, f2 = 1960.1 MHz IMD (dbc) IMD (dbc) 0 -30 3rd Order -40 5th -50 -30 3rd Order -40 5th -50 -60 -60 7th 7th -70 -70 -80 -80 0 5 10 0 15 5 Output Power (W PEP) 15 Output Power (Watts) Intermodulation Distortion vs. Output Power Intermodulation Distortion vs. Supply Voltage 0 -10 -10 IDQ = 225 mA, VDD = 28 V -20 f1 = 1990.0 MHz, f2 = 1990.1 MHz 3rd Order -50 POUT = 10 W (PEP) -20 -30 -40 f1 = 1960.0 MHz -15 IMD3 (dB) IMD (dbc) 10 5th f2 = 1960.1 MHz IDQ = 225 mA -25 -30 -35 -60 7th -40 -70 POUT = 5 W (PEP) -45 -80 0 5 10 20 15 22 26 28 30 Supply Voltage (Volts) Output Power (Watts) Supply Current vs. Supply Voltage Supply Current vs. Bias Voltage 500 235 400 Supply Current (mA) Supply Current (mA) 24 VDD = 28 V 300 200 100 0 230 225 220 215 Vbias = 12.0 V 210 205 8 9 10 11 12 13 14 20 22 24 26 Supply Voltage (Volts) Bias Voltage (V) 3 28 30 e PTH 31042 Schematic 4 e PTH 31042 Package Mechanical Specifications Unless otherwise specified, all tolerances are 0.005 [0.127] Package A Ericsson Components RF Power Products 675 Jarvis Drive Morgan Hill, CA 95037 USA Telephone: 408-778-9434 1-877-GOLDMOS (1-877-465-3667) e-mail: rfpower@ericsson.com www.ericsson.com\rfpower 5 Specifications subject to change without notice.
