SST12LN01 2.4-2.5 GHz WLAN Low-Noise Amplifier Features 1.0 PRODUCT DESCRIPTION Gain: SST12LN01 is a cost effective Low-Noise Amplifier Typically 13.5 dB gain across 2.42.5 GHz (LNA) which requires no external RF-matching compo- nents. This device is based on the GaAs pHEMT tech- Noise Figure: nology, and complies with 802.11 b/g applications. Typically 1.5 dB across 2.42.5 GHz SST12LN01 provides high-performance, low-noise, P1dB: and moderate-gain operation within the 2.42.5 GHz Typically -5dBm with V 3.3V DD frequency band. Across this frequency band, the LNA Low-Current Consumption typically provides 13.5 dB gain and 1.5 dB noise figure. 10 mA across 2.42.5 GHz This LNA cell is designed with a self DC-biasing 50 Input/Output Matched scheme, which maintains low DC current consumption, Packages available nominally at 10 mA, during operation. Optimum perfor- 6-contact UQFN 3 mm x 1.6 mm mance is achieved with only a single power supply, and no external bias resistors or networks are required. The All non-Pb (lead-free) devices are RoHS input and output ports are single-ended 50 matched. compliant RF ports are also DC isolated requiring no DC blocking capacitors or matching components. Applications SST12LN01 is offered in a 6-contact UQFN package. WLAN See Figure 3-1 for pin assignments and Table 4-1 for Bluetooth pin descriptions. Wireless Network 2015 Microchip Technology Inc.
