SBOS730A – APRIL 2015 – REVISED MAY 2015 LMH6401 DC to 4.5 GHz, Fully-Differential, Digital Variable-Gain Amplifier
1 Features 3 Description The LMH6401 is a wideband, digitally-controlled,
variable-gain amplifier (DVGA) designed for dc to
radio frequency (RF), intermediate frequency (IF),
and high-speed time-domain applications. The device
is an ideal analog-to-digital converter (ADC) driver for
dc-or ac-coupled applications that require an
automatic gain control (AGC). 1 3-dB Bandwidth: 4.5 GHz at 26-dB Gain
Gain Range: –6 dB to 26 dB in 1-dB Steps
Differential Input Impedance: 100 О©
Differential Output with Common-Mode Control
Distortion at Max Gain (VO = 2 VPPD, RL = 200 О©):
– 200 MHz: HD2 at –73 dBc, HD3 at –80 dBc
– 500 MHz: HD2 at –68 dBc, HD3 at –72 dBc
– 1 GHz: HD2 at –63 dBc, HD3 at –63 dBc
– 2 GHz: HD2 at –58 dBc, HD3 at –54 dBc
Output IP3: …
