ASF250 5 ~ 1000 MHz MMIC Amplifier Features Description 16.9 dB Gain at 150 MHz The ASF250, a IF gain block amplifier MMIC, has a high linearity, high gain, and high efficiency over a wide range of frequency, being suitable for use in both receiver and transmitter of telecommunication systems up to 1 GHz. It has an active bias network for stable current over temperature and process variation. The amplifier is available in a SOT89 package and passes through the stringent DC, RF, and reliability tests. 22 dBm P1dB at 150 MHz 43 dBm Output IP3 at 150 MHz 2.5 dB NF at 150 MHz MTTF > 100 Years Single Supply Minimal External Components ASF250 Package Style: SOT89 Typical Performance (Supply Voltage = Device Voltage, TA = +25 C, Z0 = 50 ) Application Circuit Parameters Units Typical Frequency MHz 70 150 300 450 900 150 Gain dB 17.0 16.9 16.7 16.6 16.1 16.8 S11 dB -15 -20 -20 -20 -14 -20 IF (50 ~ 1000 MHz, 4.6 V, 90 mA) S22 dB -16 -20 -20 -19 -13 -20 IF (350 ~ 470 MHz, 5V) Output IP3 dBm 40.01) 43.01) 43.01) 40.01) 38.01) 41.52) Noise Figure dB 2.5 2.5 2.7 2.7 2.7 2.4 Output P1dB dBm 22 22 22 22 22 21 Current mA 98 98 98 98 98 90 Device Voltage V +5.0 +5.0 +5.0 +5.0 +5.0 +4.6 IF (50 ~ 1000 MHz, 5 V) IF (100 ~ 200 MHz, 5V) 1) OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 1 MHz 2) OIP3 is measured with two tones at an output power of +7 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.
