- 13.0 dB Gain at 2000 MHz ·21.5 dBm P1dB at 2000 MHz ·37.5 dBm Output IP3 at 2000 MHz ·0.9 dB NF at 2000 MHz ·MTTF > 100 Years ·Single Supply The ASL19C, a wideband linear low noise amplifier MMIC, has a low noise and high linearity at low bias current, being suitable for use in both receiver and transmitter of telecommunication systems up to 3 GHz. S11 down to –18 dB is easily achieved for low noise application to provide a good productivity. The amplifi-er is available in an SOT-89 package and passes through the stringent DC, RF, and reliability tests. Application Circuit ·CDMA ·WCDMA Product Specifications Typical Performance

Moisture Sensitivity Level (MSL) Level 3 at 260°C reflow ESD Classification & Moisture Sensitivity Level ASL19C Pxxxx Lot No. Part No. Note: 1. The number and size of ground via holes in a circuit board is critical for thermal and RF grounding considerations. 2. We recommend that the ground via holes be placed on the bottom of the lead pin 2 and exposed pad of the device for better RF and thermal performance, as shown in the drawing at the left side.
