Product Overview
HMC433ETR is ADI(Hittite) low‑noise divide‑by‑4 RF prescaler IC. Operating DC‑8.0 GHz(square‑wave up to 8.5 GHz), it features‑150 dBc/Hz additive phase‑noise, single‑ended 50‑ohm I/O and +3V supply. Packaged in compact SOT‑26 SMD, widely used for PLL synthesizers, microwave radio and RF test‑measurement equipment.
Core Advantages
Broad 0‑8GHz Bandwidth
Stable divide‑by‑4 division, sine‑wave max 8GHz, square‑wave input up to 8.5GHz for multi‑band RF systems.
Low Additive Phase‑Noise
-150 dBc/Hz@100kHz offset, maintains high signal purity for PLL local‑oscillator circuits.
Simple Single‑Ended Interface
Internal 50Ω match, no balun needed; only external AC‑coupling capacitors required, simplifies PCB layout.
Compact SMD Package
SOT‑26 small footprint, single +3V power, suitable for space‑constrained RF transceiver modules.

Frequently Asked Questions
Q1: What do suffix E / TR mean? Difference between HMC433E and HMC433ETR?
A: E = RoHS lead‑free version; TR = Tape‑Reel packaging. HMC433E is tray packing, HMC433ETR is SMT tape‑and‑reel part, die and performance are fully identical.
Q2: Can HMC433ETR run without extra peripheral components?
A: RF ports feature internal 50‑Ohm matching, no balun required. External AC‑coupling capacitors are mandatory for IN and OUT pins for normal operation.
Q3: Are there pin‑compatible alternative frequency dividers?
A: HMC432 shares the same SOT‑26 package but it is divide‑by‑2. Not pin‑to‑pin drop‑in replacement, hardware modification is required. No direct ADI divide‑by‑4 substitute in identical footprint.
Q4: What is valid operating supply voltage?
A: Operating range +2.7V ~ +3.3V, typical +3.0V. Absolute maximum rating +3.5V. Over‑voltage will permanently destroy this GaAs chip.
Q5: Why two frequency specs: 8 GHz and 8.5 GHz?
A: Max sine‑wave input 8 GHz (standard PLL working condition). Square‑wave input can reach up to 8.5 GHz.
Q6: What is safe RF input power level?
A: Recommended working input:‑12 ~ +10 dBm. Do NOT exceed absolute maximum +15 dBm to avoid device burnout.
Q7: Is HMC433ETR ESD‑sensitive?
A: Yes, GaAs MMIC device, ESD sensitive. Anti‑static protection must be applied during handling, soldering and lab measurement.
Q8: How to request datasheet and bulk price?
A: Use quick inquiry form for datasheet, footprint library, stock verification and volume quotation.
