Product details
Overview
SA5219D,602 from NXP Semiconductors (formerly Philips) is a monolithic wideband variable gain amplifier (VGA) built on a high-speed bipolar process using the Gilbert multiplier architecture. It delivers 700 MHz bandwidth, >60 dB gain control range at 200 MHz, and 7 dB minimum noise figure, operating from a single 4.5–7.0 V supply with 43 mA typical current draw. It serves as an AGC core, impedance transformer, and balun in RF/IF signal chains for cable TV, satellite receivers, and cellular base stations.
For engineers reviewing the SA5219D,602 datasheet, SA5219D,602 pinout, SA5219D,602 application, or SA5219D,602 equivalent, key selection criteria include its differential 50 Ω output, 1 kΩ high-impedance differential input, 0–1 V linear VAGC control interface, 26 dB maximum gain differential, and ESD-protected SO-16 package compatibility with AC-coupled RF layouts.
Technical Context
The SA5219D,602 implements a two-stage architecture: a wideband Gilbert cell input stage biased by a buffered bandgap reference (VBG = 1.32 V), followed by a differential transimpedance second stage and emitter-follower output stage delivering matched 50 Ω differential outputs. Its gain control linearity (ΔG/ΔVAGC ≈ constant) enables high-fidelity AM modulation up to 20 MHz control bandwidth.
It features fully differential signal paths with independent DC isolation between INA/INB and OUTA/OUTB, requiring capacitor coupling. The on-chip 1.32 V bandgap reference (Pin 7) supports stable fixed-gain configurations via resistor division to VAGC (Pin 8), minimizing temperature drift in gain setting without introducing RF path parasitics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 700 MHz – usable small-signal gain flatness up to UHF frequencies without external tuning |
| Gain Control Range | >60 dB at 200 MHz – enables wide-dynamic-range AGC loops in cascaded configurations |
| Max Gain Differential | 26 dB – supports both low-noise (7 dB NF) and high-gain (23 dB SE / 28 dB DE) operating points |
| Noise Figure | 7 dB minimum – achieved with 200 Ω source match; degrades ~1.2 dB per 2 dB gain reduction |
| Supply Voltage | 4.5–7.0 V – single-rail operation compatible with standard logic and analog supplies |
| VAGC Input Range | 0–1.3 V – linear control interface with <−6 µA bias current, enabling simple op-amp integrator drive |

SA5219D,602 is housed in a 16-pin plastic small outline (SO) package per SOT109-1, 3.9 mm body width, lead pitch 0.65 mm, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Differential Output A | Emitter-follower output node; 50 Ω source impedance; requires AC coupling to preserve DC bias |
| 2 (VCC1) | Positive Supply Rail 1 | Primary power connection for input stage; decoupling required within 1 cm of pin |
| 3 (INA) | Inverting Input | High-impedance (1 kΩ) differential input terminal; must be DC-isolated from INB |
| 4 (GND2) | Ground 2 | Dedicated ground for output stage; separate from GND1 to minimize crosstalk |
| 5 (VCC2) | Positive Supply Rail 2 | Power for output stage; routed separately from VCC1 to suppress supply-induced gain ripple |
| 6 (GND1) | Ground 1 | Input-stage ground; kept physically isolated from GND2 on PCB to maintain PSRR >45 dB |
| 7 (VBG) | Bandgap Reference Output | Stable 1.32 V reference; drives resistor dividers for fixed-gain VAGC without loading RF path |
| 8 (VAGC) | Gain Control Input | 0–1.3 V linear control port; draws <−6 µA; integrates directly with op-amp AGC loop outputs |
| 9 (INB) | Non-inverting Input | Complementary high-Z input; DC-isolation from INA mandatory for common-mode rejection |
| 10 (GND1) | Ground 1 (redundant) | Second connection to input-stage ground plane; improves thermal dissipation and layout symmetry |
| 11 (GND2) | Ground 2 (redundant) | Second connection to output-stage ground; reduces differential output imbalance |
| 12 (OUTB) | Differential Output B | Complementary emitter-follower output; matched to OUTA for balanced signal integrity |
| 13 (GND2) | Ground 2 (redundant) | Third GND2 tie point; enhances thermal conduction and minimizes ground bounce at high frequency |
| 14 (GND2) | Ground 2 (redundant) | Fourth GND2 connection; ensures low-inductance return path for differential output currents |
| 15 (GND2) | Ground 2 (redundant) | Fifth GND2 pad; critical for maintaining 700 MHz bandwidth and reverse isolation >60 dB |
| 16 (GND2) | Ground 2 (redundant) | Sixth GND2 terminal; completes low-impedance ground ring around output pins for EMI suppression |

FAQ
What is the recommended power supply decoupling for SA5219D,602?
SA5219D,602 requires individual 100 nF ceramic capacitors placed within 3 mm of each VCC pin (Pins 2 and 5), plus a bulk 4.7 µF tantalum capacitor near the SO-16 package. Ground connections (GND1 and GND2) must be tied to separate low-inductance planes to maintain PSRR >45 dB and prevent gain ripple above 100 MHz.
Can SA5219D,602 operate with a 3.3 V supply?
No. SA5219D,602 specifies a minimum supply voltage of 4.5 V per the Recommended Operating Conditions table. Operation below 4.5 V risks insufficient headroom for the emitter-follower output stage and degraded gain flatness above 100 MHz. The SA5219D,602 is not characterized or guaranteed for 3.3 V use.
How is the VBG pin (Pin 7) used in fixed-gain configurations?
In fixed-gain mode, SA5219D,602's VBG pin provides a stable 1.32 V reference that can be resistor-divided to generate a precise DC voltage applied to VAGC (Pin 8). This eliminates temperature drift in gain setting, as the SA5219D,602's gain vs. VAGC curve remains linear and stable across −40°C to +85°C when driven from VBG.
What is the maximum input voltage swing for linear operation of SA5219D,602?
At 200 MHz, SA5219D,602 supports a maximum single-ended input voltage swing of 200 mVP-P before 1% THD. With RL = 50 Ω, overload occurs at input for single-ended gain <6 dB; with RL = 1 kΩ, overload occurs at input for single-ended gain <13 dB - values confirmed in the AC Electrical Characteristics table.
Does SA5219D,602 require external baluns for 50 Ω source matching?
SA5219D,602 does not require external baluns for basic operation but benefits from them for optimal performance. A 2:1 balun matches 50 Ω sources to the 200 Ω input for minimum 7 dB noise figure; a 4:1 balun matches to 1 kΩ for maximum 23 dB single-ended gain. The SA5219D,602's high-impedance differential input enables either choice without redesign.
