Parameter	Spec	Notes
Package	10mm x 10mm	36-pin flat-pack (same package as L-17C); The L-17D die is 80 x 120 mils (2 x 3 mm)
Rise Time/Bandwidth
inputs 40µV to 150µV	<10ns/ 40 MHz	Depends on board layout. The useable L-17C Bandwidth was about 20 MHz, full scale.
for inputs > 150µV	< 6ns/ 60 MHz
Noise (voltage/current)	1.2 nV/Hz^1/2 / 1.0 pA/Hz^1/2	@25°C; (L-17C voltage noise is ~1.5 nV/Hz^1/2)
Pulse Recovery Time	< 150ns	Does not include any detector contribution. Can be shortened with recovery nets. Has been tuned to <50ns at 0dbm with a tunnel diode.
Dynamic Range	> 90 dBV	Using a tunnel diode detector. Using a Schottky detector, a 60dBm range has been achieved.
Log Linearity	< ±0.3 dB	Over the full dynamic range
Temperature Drift	< ±0.5 dB (after trimming)	From -55°C to +85°C and higher
Transit Time	< 9 ns	Measured through the entire LVA, between the 50% points of the input and output; the spread is adjustable to <2 ns over the dynamic range.
Pulse-to-CW Variation	< 0.2 dB	A change in pulse duration from 10 ns to 1 ms (at high duty-cycle) does not affect pulse height.
LVA Power	Rail voltages ± 5V to ± 9V	Special regulation or dual-tracking not required. Quiescent power draw is ~ 375 mW at ± 6V. Currents at ± 6V are 31mA from the positive supply and 32 mA from the negative supply.
Output Offset	Adjustable	Maximum output voltage is +5V (rails at ±9V). Will drive a 50 Ω cable for outputs up to 4 V.
Output Slope	Adjustable
Output Load	≥50 ohms
