ASL19C 5-3000 MHz High Linearity LNA MMIC Features Description ·13.0 dB Gain at 2000 MHz 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 amplifier is available in an SOT-89 package and passes through the stringent DC, RF, and reliability tests. ·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 Typical Performance Parameters ASL19C Package Style: SOT-89 Application Circuit Units ·CDMA Typical ·WCDMA Frequency MHz 850 2000 Gain dB 19.5 13.0 S11 dB -18 -18 S22 dB -13 -14 Output IP31) dBm 35.5 37.5 Noise Figure dB 0.8 0.9 Output P1dB dBm 21.0 21.5 Current mA 68 68 V 4.0 4.0 Device Voltage 1) OIP3 is measured with two tones at an output power of +10 dBm/tone separated by 1 MHz.

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.
