Matched Broadband RF VGA 400MHz to 2700MHz Glitch-Free TM , Zero-Distortion TM , RF VGA 1 Rev 3, April 2015 IDTF0480NBGI Datasheet G ENERAL D ESCRIPTION This document describes the specifications for the IDTF0480 400 MHz to 2700 MHz RF Digital Variable Ga in Amplifier used in receiver, transmitter and other applications. IDTF0480 RF DVGA provides 13 dB typical maximum gain (no attenuation) with 4 dB noise figure and 23 dB gain adjustment in 1 dB steps designed to operate with a single 5 V supply. Nominally, the device of fers +41 dBm output IP3 using 100 mA of I CC . This device is packaged in a 5x5 32)pin thin QFN with 50 ohm single)ended RF input and RF output impedances for ease of integration into the signal)path lineup. C OMPETITIVE ADVANTAGE In many applications, digital step attenuators followed by RF amplifiers are used in the Receive path. The IDTF0480 RF DVGA provides very high reliability by combining a silicon Glitch)Free TM DSA & a Zero) Distortion TM RF amplifier in a single, compact QFN package. Utilizing IDT’s technology, the resultant RF VGA provides +41 dBm OIP3 performance across a very wide bandwidth of 400 MHz to 2700 MHz at approximately 100 mA of current. Furthermore the device is internally matched so there is no need to optimize external matching elements.

Matched Broadband RF VGA 400MHz to 2700MHz Glitch-Free TM , Zero-Distortion TM , RF VGA 18 Rev 3, April 2015 IDTF0480NBGI Datasheet STABILITY CONSIDERATIONS The IDTF0480 EVkit is unconditionally stable as sho wn on page 14, bottom right graph. One can ensure that the device itself is unconditio nally stable (Rollett Stability factor [K] > 1) regardless of trace and connector losses present in the actual application by adding a shunt 500 ohm resistor at the output. For the HB configuration , it is also advised to change R8 to 400K and C5 to 4.7 pF. This 500 ohm shunt load will reduce the gain by abo ut 0.4 dB but leave the rest of the performance par ameters such as IP3, S22, etc. virtually unchanged. The 500 ohm shunt load will ensure that the device is unconditionally stable WITHOUT the presence of t he input and output traces and connectors associated with the EV kit. In all cases we do recommend that the output capacitor, C5, be placed as close to the output of the package as possible.

Must use external DC block as close to the pin as possible. 33 — EP Exposed Pad. Internally connected to GND. Solder th is exposed pad to a PCB pad that uses multiple ground vias to provide heat transfer out of the device into the PCB ground planes. These multip le via grounds are also required to achieve the noted RF performance. 1. The SPI interface should be built up by an 8)bit word where 5 bits are used for attenuation setting (s ee F0480 DVGA Attenuation word truth table above).

Matched Broadband RF VGA 400MHz to 2700MHz Glitch-Free TM , Zero-Distortion TM , RF VGA 26 Rev 3, April 2015 IDTF0480NBGI Datasheet APPLICATIONS INFORMATION IDTF0480 has been optimized for use in high perform ance RF applications from 700 MHz to 2700 MHz. Power Supplies A common VCC power supply should be used for all pi ns requiring DC power. All supply pins should be bypassed with external capacitors to minimize noise and fast transients. Supply noise can degrade noi se figure and fast transients can trigger ESD clamps a nd cause them to fail. Supply voltage change or tr ansients should have a slew rate smaller than 1V/20µS. In a ddition, all control pins should remain at 0V (+/)0 .3V) while the supply voltage ramps or while it returns to zero. Control Pin Interface If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, unde rshoot, ringing, etc., the following circuit at the input of each control pin is recommended. This applies to SPI and control pins 8, 9, 10, 11, 15, and 17 as shown below. Note the recommended resistor and capacitor val ues do not necessarily match the EV kit BOM for the case o f poor control signal integrity. For multiple devi ces driven by a single control line, the component values will need to be adjusted accordingly so as not to overl oad the control line 16 25
