Overall Summary: The LM3046 NPN (Bipolar) Transistor Array contains 5 medium performance switching transistors suitable for general purpose, low current audio and RF applications up to 30 MHz. Higher frequency operation may benefit from discrete devices with higher FT (e.g. 8 GHz and above)
This IC will be used as a receiver mixer with Radio Frequency (RF) and Local Oscillator (LO) inputs and produce an Audio Frequency (AF) output based on a Direct Conversion (DC) approach. It will also be used as the active component in a Varicap Tuned VCO required for "on frequency" LO synthesis.
 | VBE = 0.72 Volts (approximately) at IC = 1 mA, VCE = 3 V and T = 25 C |
| The temperature gradient of VBE is approximately -1.83 mV / C at IC = 1 mA |
| Maximum common emitter current gain (Beta Ratio) hFE = 110 occurs at IC = 4.0 mA |
| Maximum common emitter Transition Frequency (Frequency where Beta = 1) FT = 580 MHz also occurs at IC = 4 mA. |
| The LM3046 Array is a general purpose NPN array so its device Noise Figure is not exceptional (NF > 2 dB at RS = 1 kŲ) |
