1 Introduction
The THS6222RHFEVM is an evaluation module for the single THS6222 amplifier in the RHF package.
This evaluation module is designed to quickly and easily demonstrate the functionality and versatility of
the amplifier. The EVM is ready to connect to power, signal sources, and test instruments through the use
of onboard connectors. The EVM comes configured for easy connection with common 50-
Ω laboratory
equipment on its inputs and outputs. The amplifier is configured for a differential input with a gain of 10
V/V to a differential output. The board includes jumpers to easily switch the device between different bias
modes and a potentiometer to set the value of the IADJ pin. The EVM can be easily configured for other
gains and for single- or split-supply operation. The output transformer and resistors are configured to
present a 50-
Ω , single-ended output.
1.1 Features
• Configured for split-supply operation and easily modified for single supply
• Default gain of 10-V/V configuration can easily be reconfigured for other gains
• Designed for easy connection to standard 50- Ω input/output impedance test equipment
• Inputs and outputs include subminiature version A (SMA) connectors
1.2 EVM Specifications
Table 1 lists the typical performance specifications for the THS6222RHFEVM.
Table 1. THS6222RHFEVM Specifications
Specification Typical Value Range
Split-supply voltage range ±4 V to ±26 V
Single-supply voltage range (VEE = ground) 8 V to 32 V
Quiescent current (no load, split supply, full-bias mode) 20.5 mA
Output voltage swing (VCC = 12 V, 100- Ω load) 19.6 V
PP
Linear output current (VCC = 12 V, 25- Ω load) 355 mA
2 Power Connections
The THS6222RHFEVM is equipped with a wire socket for easy connection of power. The positive supply
input is labeled V+, the negative supply input is labeled V–, and ground (GND) is the unlabeled center
terminal of the power-supply connector.
2.1 Split-Supply Operation
To operate as a split supply, apply the positive supply voltage to V+, the negative supply voltage to V–,
and the ground reference from supply to GND.
2.2 Single-Supply Operation
To operate as a single supply, connect both the V– connector and the GND connector to ground and
apply the positive supply voltage to V+.
