| Cascadable Amplifier 5 to 250 MHz Features * * * * HIGH GAIN - TWO STAGES: 31 dB (TYP.) MEDIUM OUTPUT LEVEL +8.5 dBm (TYP.) WIDE POWER SUPPLY RANGE +8 TO +15 VOLTS LOW VSWR: <1.3:1 (TYP.) A74-1/ SMA74-1 V2 Product Image Description The A74-1 RF amplifier is a discrete hybrid design, which uses thin film manufacturing processes for consistent performance and high reliability. This 2 stage bipolar transistor feedback amplifier design displays impressive performance over a broadband frequency range. An active DC biasing network insures temperature-stable performance. Both TO-8 and Surface Mount packages are hermetically sealed, and MIL-STD-883 environmental screening is available Ordering Information Part Number A74-1 SMA74-1 CA74-1 Package TO-8 Surface Mount SMA Connectorized Electrical Specifications: Z0 = 50, VCC = +15 VDC Typical Parameter Frequency Small Signal Gain (min) Gain Flatness (max) Reverse Isolation Noise Figure (max) Power Output @ 1 dB comp.
