The MGA-31x89 power amplifier family is optimized for frequency in order to deliver improved performance across all the major cellular bands — GSM, CDMA, and UMTS — plus next-generation LTE bands. The new gain blocks join with the 0.25-watt MGA-31189 and MGA-31289 devices and the 0.10-watt MGA-31389 and MGA-31489 devices to serve applications from 50 to 3000 MHz.
MGA-31x89 devices are all available in the compact, industry-standard SOT-89 package. Sharing a common footprint and PCB layout allows a single design to support multiple frequencies and geographic markets with a choice of output power. The gain blocks can also replace existing market solutions as a pin-to-pin, drop-in replacement offering better linearity and power performance. The devices' high gain can reduce the total number of RF stages needed. The performance gains of the MGA-31x89 family are made possible by Avago's proprietary, 0.25 µm GaAs Enhancement-mode pHEMT semiconductor process.
Performance:
At the typical operating condition of 5V and 146 mA, the MGA-31589 device delivers performance of 20.4 dB Gain, 45.3 dBm Output Third Order Intercept Point (OIP3), 27.2 dBm Output Power at 1 dB Gain Compression (P1dB) and 1.9 dB noise figure at 900 MHz. In addition, the MGA-31589 device delivers superior gain flatness of less than 0.2 dB across 100 MHz bandwidth. At the typical operating condition of 5V and 168 mA, the MGA-31689 device delivers performance of 18.1 dB Gain, 44.9 dBm Output Third Order Intercept Point (OIP3), 27.6 dBm Output Power at 1 dB Gain Compression (P1dB) and 1.9 dB noise figure at 1900 MHz. The MGA-31689 device also delivers superior gain flatness of less than 0.2 dB across 100 MHz bandwidth.
Additional Features:
- Input and output pre-matched, thus only requiring a minimum amount of external RF matching components
- Excellent uniformity in product specifications to minimize yield impact
- RoHS-Compliant and MSL-1 rated SOT-89 package: lead and halogen free
