The amplifier provides over 15dB of linear gain into 50 Ω at 400MHz. Gain control is also provided with over 70dB of dynamic range. The SL6140 offers over 45dB of voltage gain with an R L of 1kΩ. DS2159 Issue no 5.0 July 1999 Ordering Information SL6140/NA/MP Industrial temperature range miniature plastic package SL6140/NA/MPTC Tape and Reel Figure 1 Typical Application 10n 10n 10n 10n 1.0 F +VCC 2 6 5 4 37 +VCC OUTPUT OUTPUT RL RL RAGC AGC INPUT INPUT SL6140 8 1 The SL6140 (Figure 3) is a high gain amplifier with an AGC control capable of reducing the gain of the amplifier by over 70dB. The gain is adjustable by applying a voltage to the AGC input via an external resistor (R AGC), the value of which adjusts the curve of gain reduction versus control voltage (see Figure 4). As the output stage of the amplifier is an open collector the maximum voltage gain is determined by R L. With load resistance of 1k Ω the single ended voltage gain is 45dB and with a load resistance of 50 Ω the voltage gain is 15dB (20log 10 V OUT/VIN). Another parameter that depends on the load resistance is the bandwidth: 25MHz for R L = 1kΩ, as compared with 400MHz for R L = 50Ω. RL is chosen to give either the required bandwidth or voltage gain for the circuit. Figure 7 through to 10 show the typical S parameters for the device. Figures 11 and 12 show the typical variation in 3rd order intercept performance with AGC. In any application, the substrate should be connected to the most negative point in the circuit, usually to the same point as pin 3. |
