ESD Rating* AGR19060E HBM MM CDM Minimum (V) 500 50 1500 Class 1B A 4 EDGE Features Typical EDGE performance (1960 MHz, 26 V, IDQ = 500 mA): — Output power (POUT): 25 W. — Power gain: 15.3 dB. — Efficiency: 37%. — Modulation spectrum: @ ±400 kHz = –61.0 dBc. @ ±600 kHz = –74.0 dBc. — Error vector magnitude (EVM) = 2.5%. * 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. AGR19060E 60 W, 1930 MHz—1990 MHz, PCS LDMOS RF Power Transistor Electrical Characteristics Table 1.
