A7608SA-H - LTE Cat 4 Module 150Mbps | SIMCom | IoT
MPN： A7608SA-H ✓ 啟用中A7608SA-H 概覽
An LTE Cat 4 module is a cellular communication device classified under the 3GPP LTE standard category that supports peak downlink rates around 150 Mbps using 2x2 MIMO. Within the hierarchy of RF modules, it sits between low-bandwidth Cat-M1/NB-IoT modules and higher-rate Cat 6+ modules, making it a workhorse choice for mainstream IoT broadband links.
Key features include multi-band LTE-FDD/LTE-TDD operation with fallback to HSPA+ and GSM/EDGE, a 4-bit SD/MMC interface clocked up to 200 MHz compatible with SDIO Card Specification version 3.0 (up to 32 GB cards), and abundant industrial-standard interfaces such as UART, USB, I2C, and GPIO with powerful expandability.
Technically, the module integrates built-in network protocol stacks and provides USB drivers for Windows, Linux and Android, allowing rapid host integration without external protocol processors. GNSS positioning support and voice/SMS functionality simplify telematics and tracking designs that previously required separate receivers.
Typical applications include telematics units, surveillance devices, CPE customer-premises equipment, industrial routers, and remote diagnostics systems, where the 150 Mbps downlink supports video streaming and cloud dashboards.
Design consideration: the module is supplied on a 3.x V VBAT rail; follow the manufacturer user manual absolute maximum ratings for VBAT, USB_VBUS and digital pins, and provide adequate RF layout area for the 30x30 mm LCC+LGA castellation footprint.

典型應用
A7608SA-H 適用於 6 應用s: Industrial Routers, CPE (Customer Premises Equipment), Telematics and Fleet Tracking, Surveillance and Security Devices, Remote Diagnostics, IoT Gateways and Smart Devices.
Industrial Routers
Industrial routers require a broadband cellular backhaul that stays online across 4G, 3G and 2G coverage gaps. The A7608SA-H fits this role with LTE Cat 4 peak rates of 150 Mbps downlink and 50 Mbps uplink, plus automatic fallback to HSPA+, GSM, GPRS and EDGE where LTE is unavailable. Its UART provides a control path for MCU-based router designs, while the high-speed USB interface carries the full-rate data path with native Windows, Linux and Android drivers, eliminating external protocol conversion. The 4-bit SD/MMC interface (up to 200 MHz, SDIO v3.0, 32 GB cards) supports local logging storage. Because AT commands match the SIM7600 series, router firmware developed for SIM7600 ports with minimal rework, and the shared LCC+LGA footprint reuses existing PCB layouts.
推薦
CPE (Customer Premises Equipment)
Fixed-wireless CPE devices demand near-broadband throughput and carrier robustness. The A7608SA-H delivers LTE Cat 4 performance up to 150 Mbps DL, sufficient for household video streaming and multi-device NAT routing when paired with an external antenna and router SoC. Built-in network protocol stacks and multi-OS USB drivers let a Linux-based CPE host bring up the WAN link quickly. The module's castellated LCC+LGA pads permit automated assembly directly onto the CPE mainboard, avoiding connector cost and reliability issues. Migration compatibility with SIM5320/SIM5360 and SIM7600/SIM7600-H footprints means CPE vendors can maintain one PCB across 3G and 4G product tiers, reducing certification and tooling spend when refreshing product lines from 3G to LTE.
推薦
Telematics and Fleet Tracking
Telematics units combine positioning, cellular reporting and local logging in a compact, cost-sensitive package. The A7608SA-H addresses all three needs: LTE Cat 4 cellular connectivity with 2G/3G fallback ensures data delivery in mixed-coverage rural routes; the A7608 platform includes GNSS positioning support for location fix without a separate receiver; and the SD/MMC interface supports up to 32 GB cards for offline trip-data buffering. UART-based control suits low-power MCU hosts, while the SIM7600-compatible AT command set lets existing fleet-tracking firmware migrate without protocol changes. Distributors position the A7608SA-H explicitly for telematics, citing its strong rural signal handling and documented driver resources as practical advantages for long-lifetime vehicle installations.
推薦
Surveillance and Security Devices
IP cameras and security gateways need enough uplink bandwidth for continuous video streams. The A7608SA-H's 50 Mbps LTE uplink accommodates mainstream H.264/H.265 camera streams, while the 150 Mbps downlink supports cloud dashboard access and remote firmware updates. Its built-in network protocols and Android/Windows/Linux drivers integrate directly with camera SoC platforms over USB. The module suits surveillance devices per SIMCom's own application targeting, and its LCC+LGA footprint supports dense multi-camera NVR boards. For sites deploying mixed 3G/4G hardware, the SIM5360 and SIM7600 footprint compatibility allows one camera PCB to serve legacy and LTE SKUs, simplifying spare-part logistics and letting integrators upgrade deployed sites by module swap rather than full hardware replacement.
推薦
Remote Diagnostics
Remote diagnostics equipment - from vehicle OBD gateways to industrial machine-health loggers - requires dependable low-to-medium bandwidth cellular links with local storage. The A7608SA-H provides GSM/GPRS/EDGE fallback for areas without LTE, ensuring diagnostic heartbeat messages always get through, while Cat 4 rates enable rapid bulk log upload when high-speed coverage is present. The 4-bit SD/MMC interface at up to 200 MHz (SDIO v3.0, 32 GB max) buffers diagnostic records locally during outages. I2C and GPIO interfaces connect sensor front-ends and status indicators without extra expanders. Because AT commands match SIM7600 series, diagnostic firmware libraries written for SIM7600 run unchanged, and community resources such as the LilyGO A76XX repositories document pinmaps and drivers for rapid prototyping.
推薦
IoT Gateways and Smart Devices
Cellular IoT gateways aggregate sensor traffic and bridge it to cloud platforms. The A7608SA-H fits between NB-IoT modules (too slow for aggregated traffic) and Cat 6 modules (over-specified and costlier), offering 150/50 Mbps Cat 4 throughput that comfortably handles dozens of concurrent sensor sessions plus OTA updates. Built-in TCP/IP protocol stacks offload connectivity management from the gateway MCU, and the UART/USB/I2C/GPIO interface set covers both data-path and control-path needs of typical gateway boards. Its RoHS-compliant LCC+LGA 30x30 mm package assembles with standard reflow processes. The smooth migration path from SIM5320/SIM5360 3G designs lets gateway vendors sunset 3G SKUs as carriers retire legacy networks, protecting long-term product roadmaps.

主要差異化特點
- Lower cost within the same LTE Cat 4 performance class (對比SIM7600SA-H)
- Three-generation footprint migration path (對比SIM5360)
- Trade-off: family band variants instead of a single global SKU (對比A7608E-H)
設計說明
The A7608SA-H uses a 172-pad LCC+LGA castellation footprint of 30x30 mm. Follow the SIMCom hardware design guide for pad geometry and keep-out: reserve clearance under the module for RF trace routing to the antenna pad, and follow the reference footprint in the A7608SA-H User Manual V1.00. Because the footprint is shared with SIM5320/SIM5360 and SIM7600/SIM7600-H modules, design the land pattern from the common SIMCom footprint document so a single PCB can accept any of these modules for 3G-to-LTE migration.
Cellular modules exhibit high burst current during RF transmit bursts. Size the VBAT supply and bulk capacitance per the absolute maximum and electrical specifications tables in the A7608SA-H User Manual (Table 28 lists maximum ratings for VBAT, USB_VBUS and digital pins such as RESET and SPI). Place low-ESR bulk capacitance close to the VBAT pads; insufficient supply impedance during bursts is the most common cause of module resets and dropped registrations in the field.
Although AT commands are SIM7600-compatible, confirm feature-level differences before firmware reuse: verify GNSS and voice/SMS support for your specific A7608SA-H firmware build, and validate the USB descriptor behavior under your Windows/Linux/Android driver version. The SD/MMC interface runs at 2.95 V and supports SDIO v3.0 cards up to 32 GB - do not connect 1.8 V-only cards or assume higher-capacity SDXC behavior without SIMCom validation.
