F2480EVBI

Broadband RF Analog VGA F2480 400 to 3000 MHz Datasheet Description Features The F2480 is a 400 to 3000 MHz RF Analog Variable Gain 400 to 3000 MHz (Amplifier Range) Amplifier (AVGA) that can be used in receivers, transmitters and 50 to 6000 MHz (Attenuator Range) other applications. Either the amplifier or voltage variable 12dB typical cascaded max gain attenuator (VVA) can be configured as the first stage in the 36dB continuous gain range cascade. Excellent linearity +41.5dBm OIP3 The F2480 RF AVGA provides 12dB typical maximum cascade Noise Figure 4.3dB gain (no attenuation) with 4.3dB noise figure (amplifier as first stage) and 36dB gain adjustment designed to operate with a I = 106mA CC single +5V supply. Nominally, the amplifier offers +41.5dBm 1.2mA Amplifier Standby Current output IP3 using 106mA of I . CC Bi-directional attenuator RF ports This device is packaged in a 5 x 5 mm, 32-pin TQFN with 50 Positive amplifier gain slope vs. frequency to counteract single-ended RF input and RF output impedances for ease of system PCB loss. integration into the signal-path lineup. V pin allows either positive or negative attenuation control MODE response Linear-in-dB attenuation characteristic Competitive Advantage 4 RF Port pinout supporting multiple lineup configurations 50 input and output impedances The F2480 RF AVGA provides very high-performance by combining a silicon VVA & a Zero-Distortion RF amplifier in a Broadband, Internally Matched single, compact TQFN package. Because of the superb VVA IP3 5 x 5 mm, 32-pin TQFN package performance over its full attenuation range, the VVA can be placed after the amplifier while yielding the desired cascaded OIP3 performance. Utilizing IDTs technology, the resultant RF AVGA provides +41.5dBm OIP3 performance at 900MHz. The Block Diagram device is internally matched so there is no need to optimize external matching elements. Figure 1.
