Product details
Overview
SA630D/01,118 from NXP Semiconductors is a BiCMOS-based Single-Pole Double-Throw (SPDT) RF switch optimized for DC–1 GHz signal routing in 50 Ω systems. It features 1 dB typical insertion loss at 200 MHz, 60 dB off-channel isolation at 100 MHz, and consumes only 170 μA from a 5 V supply-enabling low-power portable transceiver front-ends.
For engineers reviewing the SA630D/01,118 datasheet, SA630D/01,118 pinout, SA630D/01,118 application, or SA630D/01,118 equivalent, key selection criteria include its TTL/CMOS-compatible ENCH1 control, internal 50 Ω OFF-channel termination, bidirectional operation, and fast 20 ns switching with minimal transient voltage (165 mVp-p).
Technical Context
The SA630D/01,118 implements a single-pole double-throw topology with on-chip CMOS/TTL drivers and integrated 50 Ω termination on the inactive channel. Its BiCMOS process enables high linearity (IP3 = +33 dBm) and robust overload capability (+18 dBm 1 dB compression point at 300 MHz).
Control logic is level-sensitive: applying a logic HIGH (≥2.0 V) to ENCH1 connects INPUT to OUT1; logic LOW (≤0.8 V) routes INPUT to OUT2. AC_GND (pin 7) requires external 0.01 μF bypassing to maintain RF performance across frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 1 GHz - supports broadband RF routing without external tuning components |
| Insertion Loss | 1 dB typical at 200 MHz - minimizes signal attenuation in active path |
| Isolation | 60 dB at 100 MHz - ensures strong channel separation in antenna or filter selection |
| Supply Current | 170 μA at 5 V - enables battery-powered operation with negligible quiescent drain |
| Switching Time | 20 ns typical turn-off delay - supports high-speed modulation schemes like FSK |
| Input Power Handling | +20 dBm maximum - withstands typical transmitter output levels without damage |
| Third-Order Intercept | +33 dBm at 100 MHz - maintains signal integrity in multi-tone environments |
| Return Loss | 18 dB at 400 MHz - indicates good 50 Ω match, reducing reflections in RF traces |
Pinout & Package
SA630D/01,118 is housed in an 8-pin SO (SO8, SOT96-1) surface-mount package with 3.9 mm body width and standard lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (pin 1) | Power supply input | Accepts 3.0–5.5 V DC; powers internal BiCMOS switch core and drivers |
| GND (pins 2, 6) | Ground reference | Dual ground pins reduce impedance and improve RF return path stability |
| INPUT (pin 3) | Common RF port | Bidirectional RF node shared by both SPDT paths; 50 Ω matched |
| ENCH1 (pin 4) | Channel select control | CMOS/TTL-compatible enable: HIGH → INPUT→OUT1; LOW → INPUT→OUT2 |
| OUT2 (pin 5) | RF output (channel 2) | Active when ENCH1 = LOW; internally terminated to 50 Ω when OFF |
| AC_GND (pin 7) | RF ground bypass | Must be decoupled with 0.01 μF capacitor close to package for optimal isolation |
| OUT1 (pin 8) | RF output (channel 1) | Active when ENCH1 = HIGH; matches OUT2 in loss and return loss up to 1.2 GHz |
Key Features
| Feature | Design Value |
|---|---|
| Wideband operation | DC–1 GHz range eliminates need for band-specific switches in multi-band radios |
| Internal 50 Ω termination | Removes requirement for external termination resistors on OFF channel |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11036 | Higher frequency range (DC–3.5 GHz), higher supply current (2.5 mA), no internal 50 Ω termination | Requires external termination resistors; suited for 5G NR sub-6 GHz front-ends | Choose QM11036 when >1 GHz bandwidth or higher power handling is required |
| Analog Devices HMC349ALP4E | Wider bandwidth (DC–4 GHz), higher isolation (70 dB @ 1 GHz), GaAs process, 5 V supply | Higher cost and larger 4×4 mm QFN package; lacks CMOS-compatible control | Choose HMC349ALP4E for ultra-high isolation or millimeter-wave adjacent bands |

FAQ
What is the recommended supply voltage range for the SA630D/01,118?
The SA630D/01,118 operates over a supply voltage range of 3.0 V to 5.5 V, with typical performance characterized at +5 V. Operation below 3.0 V may degrade switching speed and isolation; exceeding 5.5 V risks permanent damage per absolute maximum ratings. The SA630D/01,118 draws only 170 μA at 5 V, making it ideal for low-power designs.
How does the SA630D/01,118 handle the OFF channel impedance?
The SA630D/01,118 internally terminates the OFF channel to 50 Ω via an on-die resistor in series with the AC_GND (pin 7) path. This eliminates the need for external termination components and ensures consistent 50 Ω match across frequency. Proper placement of a 0.01 μF capacitor on AC_GND is critical to maintain specified isolation and return loss.
Can the SA630D/01,118 be used bidirectionally?
Yes, the SA630D/01,118 supports fully bidirectional RF operation: the INPUT (pin 3) and OUT1/OUT2 (pins 5, 8) ports are interchangeable as input or output. This allows flexible use in TDD systems or shared TX/RX paths without signal direction constraints-confirmed in the device's block diagram and application schematics.
What is the thermal resistance (Rth(j-a)) of the SA630D/01,118 in its SO8 package?
The SA630D/01,118 in the SO8 (SOT96-1) package has a thermal resistance from junction to ambient of 158 °C/W under still-air conditions. This value assumes standard PCB copper pour and reflow soldering per JEDEC standards. For continuous +20 dBm operation, ambient temperature must remain ≤+85 °C to keep junction temperature within the 105 °C operating limit.
Does the SA630D/01,118 require external biasing or level-shifting for TTL/CMOS control?
No, the SA630D/01,118 features on-chip CMOS/TTL compatible drivers. ENCH1 (pin 4) accepts logic HIGH (≥2.0 V) and logic LOW (≤0.8 V) directly from standard microcontrollers or logic ICs-no external level shifters or pull-up/pull-down resistors are needed. Input current remains within ±1 μA across valid logic levels.
