Features
Typical performance for two carrier 3GPP W-CDMA systems. F1 = 2135 MHz and F2 = 2145 MHz with 3.84 MHz channel BW, adjacent channel BW = 3.84 MHz at F1 - 5 MHz and F2 + 5 MHz. Third-order distortion is measured over 3.84 MHz BW at F1 - 10 MHz and F2 + 10 MHz. Typical P/A ratio of 8.5 dB at 0.01% (probability) CCDF: -- Output power: 28 W. -- Power gain: 14 dB. -- Efficiency: 27%. -- IM3: -34.5 dBc. -- ACPR: -38 dBc. -- Return loss: -10 dB. 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, 2140 MHz, 125 W continuous wave (CW) output power. Large signal impedance parameters available.

* 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.

* 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.
