Cascadable Amplifier 10 to 250 MHz A70-1/ SMA70-1 V2 Features Product Image • AVAILABLE IN SURFACE MOUNT • LOW NOISE: 1.8 dB (TYP.) • HIGH EFFICIENCY: +14 dBm (TYP.) OUTPUT POWER AT 15 mA (TYP.) Description The A70-1 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 A70-1 TO-8 SMA70-1 Surface Mount CA70-1 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 5-300 10-250 10-250 Small Signal Gain (min) dB 8.0 7.5 7.0 Gain Flatness (max) dB ±0.3 Reverse Isolation dB 11 Noise Figure (max) dB 1.8 ±0.5 2.3 ±0.7 2.8 DC Voltage +18 V Continuous Input Power 13 dBm Short Term Input power (1 minute max.) 50 mW Peak Power (3 µsec max.) 0.5 W “S” Series Burn-In Temperature (case) +125ºC Power Output @ 1 dB comp.
