Cascadable Amplifier 20 to 250 MHz A70-3/ SMA70-3 V3 Features • • • • Product Image HIGH OUTPUT POWER: +21 dBm (TYP.) LOW NOISE: 2.8 dB (TYP.) HIGH THIRD ORDER I.P.: +40 dBm LOW DC CURRENT: 37 mA (TYP.) AT +15 Vdc Description The A70-3 RF amplifier is a discrete hybrid design, which uses thin film manufacturing processes for accurate performance and high reliability. This single stage bipolar transistor feedback amplifier design displays impressive performance over a broadband frequency range. Use of an impedance transformer offers the benefit of high dynamic range and high efficiency. Both TO-8 and Surface Mount packages are hermetically sealed, and MIL-STD-883 environmental screening is available Ordering Information Part Number Package A70-3 TO-8 SMA70-3 Surface Mount CA70-3 SMA Connectorized Electrical Specifications: Z0 = 50Ω Ω, VCC = +15 VDC Typical Parameter Absolute Maximum Ratings Parameter Absolute Maximum Storage Temperature -62ºC to +125ºC Case Temperature +125ºC Guaranteed Units 25ºC 0º to 50ºC -54º to +85ºC* Frequency MHz 15-300 20-250 20-250 Small Signal Gain (min) dB 8.0 7.0 6.5 Gain Flatness (max) dB ±0.3 Reverse Isolation dB 11 Noise Figure (max) dB 2.8 ±0.5 3.2 ±1.0 3.7 DC Voltage +17 V Continuous Input Power 15 dBm Short Term Input power (1 minute max.) 100 mW Peak Power (3 µsec max.) 0.5 W “S” Series Burn-In Temperature (case) +125ºC Power Output @ 1 dB comp.
