The Big Deal
CASE STYLE: AF320
• Super Wideband, DC to 20 GHz
• Excellent Gain Flatness(±1.1dB up to 10 GHz)
• Low Current, 19.1 mA
Product Overview
The EHC-24L+ is a low current, wideband gain block that operates up to 20 GHz fabricated using highly
reliable HBT process. This Darlington pair amplifier delivers excellent gain flatness, good return loss, low
current with acceptable P1dB and OIP3 across a wide bandwidth without the need of external matching
network. It has highly repeatable performance from lot to lot and it is enclosed in a 4-lead ceramic package.
Key Features
Feature
Advantages
Super Wideband: DC to 20 GHz
General purpose wideband amplifier is suitable for various applications.
Low Current, 19.1mA
Low current consumption is ideal for use in amplifier chain.
Excellent gain flatness
+/- 1.1dB up to 10GHz
+/- 2.7dB up to 20GHz
As a desirable characteristic of a wideband amplifier, excellent gain flatness allows
amplification of a signal without changing the waveform in time domain.
EHC-24L+ provides typical input & output return loss of 15 dB up to 20 GHz with
–
out the need for any external matching components.
No external matching component required
