AGR26045EF (flanged) Package Features Typical performance for MMDS systems. f = 2600 MHz, IDQ = 430 mA, Vds = 28 V, adjacent channel BW = 3.84 MHz, 5 MHz offset; alternate channel BW = 3.84 MHz, 10 MHz offset. Typical P/A ratio of 9.8 dB at 0.01% (probability) CCDF*: — Output power: 6.5 W. — Power gain: 13 dB. — Efficiency: 20% . — ACPR: –34 dBc. — ACLR1: –36 dBc. — Return loss: –15 dB. Typical pulsed P1dB, 6 µs pulse at 10% duty: 47 W. High-reliability, gold-metalization process. Low hot carrier injection (HCI) induced bias drift over 20 years. Internally matched. High gain, efficiency, and linearity. Integrated ESD protection. Device can withstand a 10:1 voltage standing wave ratio (VSWR) at 28 Vdc, 2600 MHz, 45 W continuous wave (CW) output power. Large signal impedance parameters available. *The test signal utilized is 4-channel W-CDMA Test Model 1. This test signal provides an equivalent reference (occupied bandwidth and waveform EPF) for the actual performance with an MMDS waveform. * Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. Table 3. ESD Rating* AGR26045EF HBM MM CDM Minimum (V) 500 50 1500 Class 1B A 4 * Although electrostatic discharge (ESD) protection circuitry has been designed into this device, proper precautions must be taken to avoid exposure to ESD and electrical overstress (EOS) during all handling, assembly, and test operations. PEAK Devices Agere employs a human-body model (HBM), a machine model (MM), and a charged-device model (CDM) qualification requirement in order to determine ESD-susceptibility limits and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used in each of the models, as defined by JEDEC's JESD22-A114B (HBM), JESD22-A115A (MM), and JESD22-C101A (CDM) standards. Caution: MOS devices are susceptible to damage from electrostatic charge. Reasonable precautions in handling and packaging MOS devices should be observed. AGR26045EF 45 W, 2.535 GHz—2.655 GHz, N-Channel E-Mode, Lateral MOSFET Electrical Characteristics Recommended operating conditions apply unless otherwise specified: TC = 30 °C.
